How to Conduct a Goose Health Examination

Updated April 10, 2020

Much like the common advice given to humans, it’s important to regularly check the health of geese with a routine physical examination rather than waiting until they’re showing signs of distress or illness. Not only will this help you get to know what all aspects of a healthy goose look and feel like, but regular handling may help keep them calm in more stressful situations. Be prepared to check them over every six to eight weeks*! For more information on why regular health examinations are important, check out our resource here.

*An Exam Every Six to Eight Weeks Means Daily Observations!

Our recommendation to conduct routine health examinations every six to eight weeks must be done in conjunction with daily observations.  Caregivers should be trained to observe animals both for behaviors that are abnormal for the species and also behaviors that are abnormal for each individual, keeping in mind issues that are common in a particular species or breed and their warning signs.  Thoughtful observation plays a crucial role in catching health issues before they progress into more serious situations.

Residents With Challenging Backgrounds

Close daily observation can be difficult with certain individuals or groups who come from challenging backgrounds. They may be more likely to hide signs of illness or injury, or may not allow you to come close enough to them to thoroughly assess their well being on a regular basis. Challenging backgrounds may include individuals who are not socialized, have lived feral, or were abused or malnourished. If you care for individuals who came from a challenging background, it is imperative to make time to foster a bond of trust so careful observation is possible. A monthly health exam is recommended for these individuals until they exhibit signs that they feel safe and you are confident that close daily observation is possible.

Problem Signals

Because their feathers are so thick, geese require a thorough examination to reveal any hidden ailments. By paying regular attention to the flock, you may see some subtle cues in the event that something is amiss. Signs of a sick, injured, or otherwise distressed goose include:

  • Hiding more often than they used to
  • Changing their daily schedule
  • Labored breathing or a constantly open mouth
  • Discharge from their eyes or nares
  • Immobility, inactivity or unresponsiveness to your approach
  • Sitting far more often than usual
  • Avoiding the rest of the flock
  • Being bullied more by the rest of the flock or a quick pecking order reduction
  • A limp in their step, standing with one foot slightly off the ground, or constantly shifting their weight
  • Unusual or abnormal droppings including all white stool, blood in stool, or worms
  • Reduced hunger or thirst, or excessive water drinking
  • An odd posture like hunching, a tucked back head, standing very upright like a penguin, or ruffled feathers
  • Partially or fully closed eyes
  • Drooping or abnormally positioned wings
  • If they lay eggs, a quick drop in egg laying
  • Pecking at or plucking their skin and feathers, or general paleness
  • A strong, foul, sour, or cheesy odor
Tail Troubles

If you notice a goose’s tail drooping constantly or bobbing as they breathe, this may signal a serious health emergency.

In cases of symptoms such as the ones above, it’s especially important to conduct a health examination on a goose. Generally, the examination should begin at their feet, working your way front and upward to their head, as the head examination can be extra stressful to a bird. It’s important to keep regular documentation of these checkups, including weight and any abnormal findings, in order to keep an easy-to-follow set of information in case a veterinarian needs the goose’s history.

Conducting The Exam

Ask An Expert

Prior to regularly conducting goose health examinations, you should have a veterinarian or compassionate care expert give you hands-on training in order to be the best goose health advocate possible. Being trained to rapidly distinguish healthy conditions from abnormalities can be crucial in early health problem detection and effective treatment!

It can be easier to conduct the examination after they’ve went to bed as they tend to be less fussy.

Hold Them Safely!

You must be very cognizant of a goose’s stress levels and breathing when handling them. Some geese are far too large to be safely picked up or turned on their side or back and just need to be held comfortably in your lap. If a goose ever seems to be very distressed, breathing heavily, or cannot breathe comfortably, you must put them down and let them rest.

Once you have the goose ready for a health examination, conduct the following observations:

When In Doubt...

Unless you are a qualified veterinarian or have been trained to handle specific conditions, The Open Sanctuary Project strongly advocates that you promptly report any health concerns you find during the course of an exam to your veterinarian or care expert. Unless they’re in a life-threatening situation, you should be your resident’s advocate, not their doctor.

Check their feet and toes

A goose should have soft, fairly smooth skin on their feet. Check for any bumps, lumps, swelling, scabs, and cuts on both the top and bottom of their feet. If there is any bulging or discoloration on their feet, ensure that they do not have bumblefoot or another infection, as this can this can cause debilitating mobility issues and if left untreated can cause life-threatening sepsis. The webbing between their toes should be smooth and supple, though it can become more dry and cracked as they age. If they have lumps of mud stuck to their feet, soak them off with warm and soapy water rather than attempting to pull them off. Don’t remove scabs! Carefully check their foot’s range of motion for cracking sounds, pain, resistance, heat, or swelling. If the goose happens to have long toenails, you can trim them.

Check their legs

A goose’s legs (also known as shanks), shouldn’t have any cuts, lumps, or any mites on them. If their legs are raw and painful, they might have Scald, which is a result of poor housing conditions leading to ammonia burns. This requires medical treatment. Carefully check their range of motion for cracking sounds, pain, resistance, heat, or swelling. Like their keel, larger geese are prone to inflammation and sores on their hocks that require vigilant attention to prevent infection. Do not attempt to drain infected joints!

Check their feathers

A goose’s feathers typically should look shiny and lay flat against them. Bloody feathers is a clear sign of a problem. Feathers should not be dirty, dull, missing, tattered, frayed, ruffled, or broken. Any of these issues could be symptomatic of a stressed out bird, parasites, flock behavior issues like boredom, bullying, over-mounting, nutritional deficiencies (especially protein), and infestations in their living space like rodents or flies. If the goose is molting, be very mindful of their pin feathers, as these emerging feathers are very sensitive to handling and can bleed quite a bit if broken. If their feathers don’t seem to be developing or won’t fold into their normal position, this is also indicative of a problem. If the goose’s feathers look damp and dirty, they might have Wet Feather, where they do not have access to clean water and a dry space to keep their feathers well-maintained.

Check their skin

Part the goose’s feathers around their body if they aren’t too sensitive. Feathers can hide skin illnesses and injuries. This is the time to ensure you are checking and feeling every area of the individual’s body, not just those included in this list.  This thorough section of the exam is critical to ensure that nothing that can be addressed early is missed. Their skin should not have lice, mites, nits, lumps, cuts, cysts, bruises, gangrene, larvae or maggots. Generally, waterfowl have very tightly packed down and do not get as many skin parasites as other birds. This tightly packed down can make it hard to see through to their skin.  Therefore, it is sometimes easier to feel for issues than to look for issues on certain parts of their body. Their skin should generally be clean and soft and pale pink and translucent. Blackened skin could indicate frostbite, which requires immediate treatment.

Check their breast

A goose’s breast should be blister-free and firm. Their keel (central breast bone) should not be sharp, protruding or bony (indicating possible weight loss), nor should it be tough to find or surrounded by fat (indicating possible obesity). The keel should not be curved, which may indicate a nutritional deficiency, especially a calcium and phosphate imbalance or a vitamin D deficiency, which could mean too many treats in their diet! Larger geese are prone to pressure sores on their keel. Any keel sores should be treated early on before they risk infection. If there’s a keel sore that moves along with the bone underneath, this could indicate that they already have a bone infection.

Check their abdomen

A goose’s abdomen should be soft, and shouldn’t be hard, fluidy, or swollen. If their abdomen feels odd, this could mean a number of serious issues including egg binding, yolk peritonitis, egg yolk impaction, a bacterial infection like salpingitis, fluid blockage, or heart failure. You should consult a veterinarian if you have abdominal concerns.

Check their preen gland

At the base of the goose’s tail is the preen gland. Apart from the lobe of the gland itself, it should not have any additional lumps or blockage. Orange-tinged oily discharge from the tip of the preen gland is normal.  Ensure that it does not have any parasites around it. An enlarged preen gland could indicate impaction or cancer. Impaction can be handled with a warm compress periodically applied to their preen gland, but it should be evaluated by an expert before beginning treatment.

Check their vent

A goose’s vent (a fancy way to say their butt), should be clean and moist (but not wet). It shouldn’t have any discharge, excessive accumulations of fecal matter around it, nor should it be crusty, bloody, or dry. Check for rat wounds, as this is where they tend to bite; the presence of rat wounds is a major red flag that you must control your rodent population before they cause more damage. Ensure that it doesn’t have any mites, lice, tapeworms, or other parasites. Make sure that the vent (and in the case of male geese, their penis) isn’t irritated or prolapsed (protruding). If it’s prolapsed, you should consult with a veterinarian.

Check their wings

Take a look at the goose’s wings. You will likely have to check the wing held close to you in a later part of the examination when you reposition them to check their crop. They should be held close to their body, generally symmetrical, and there should be movement in their wings’ joints when they flex. A goose’s wings should be checked for cuts, swelling, and other injuries. Make sure to check the area underneath their wings for lice and mites.

Check their crop

A goose’s crop is at the base of their neck before it meets the chest. If holding the goose close to your chest up until this point, you will likely have to set the goose onto the ground (while keeping them secure) in order to check their crop. Though smaller and more difficult to evaluate than a chicken’s, their crop is the area is where food is stored before entering a goose’s stomach. It should feel empty (or impossible to feel at all) before they eat for the day or after digestion, and full after eating, though in general, feeling “nothing” is normal. Be careful when checking the crop as it may be filled with water the goose just drank, and you could cause them to regurgitate. If the crop is hard this indicates a problem. If the goose has bad or sour-smelling breath, this also indicates possible crop issues, such as sour crop, which is a fungal yeast infection that requires treatment. If the crop remains full and firm and they haven’t eaten in a while (or overnight), the crop could be impacted (or blocked). If you are concerned about a goose’s crop, you should consult a veterinarian. It’s important to get to know what a crop feels like both full and empty so you can more easily monitor it for abnormalities. Make sure the goose has appropriate grit for healthy digestion!

Check their head

How are they holding their head? It’s best if they’re holding it up on their own volition. If they’re shaking, hunching, or tucking their head, this could indicate illness or injury. Their ears should not have any discharge coming from them, which could indicate an infection.

Check their eyes

A goose should have wide open, clean, alert eyes. They should be free of discharge and clear. Cloudy, watery, dry, swollen, or crusty eyes indicates likely illness or injury. Their pupils should be about the same size and react properly to bright light (get smaller and then return to normal). Geese have a third eyelid, known as the nictitating membrane. It should be cloudy white and retract when stimulated, rather than red, swollen, or non-retractable.

Check their bill

Is the goose’s bill open or closed? If mostly open, they may be stressed, overheated, or have a respiratory illness. Their nares (goose nostrils) should be free of scratches, bubbles, discharge, and general crustiness. In general, you should be able to see clear through from one nare to the other. A hot bill could indicate a fever or pneumonia. Drooling could indicate a blocked crop, requiring veterinary intervention. Bloody discharge from their nose could be indicative of Duck Virus Enteritis. If their bill or nares needs cleaning, use a soft cloth rather than your hand as the bill can be damaged by excessive pressure.

Check their mouth

A goose’s mouth should not be foaming or contain discharge. You shouldn’t be able to hear them breathe in ideal circumstances. Their breathing should not be labored, loud, wheezy, rattly, sneezy, whistling, or squeaky. Now look inside their mouth (especially at their tongue). They should not have any ulcers, lesions, lumps, or discoloration. If there are lesions that look “cheesy”, this could be due to mold toxicity or Wet Fowl pox. Their mouth shouldn’t have a strange odor. If they do, they may have sour crop. Sticky saliva could indicate dehydration.

Check their weight and body condition

It’s important to know the accurate weight of each of the birds in your care, as a healthy adult goose should maintain weight consistently. If a bird has lost a lot of weight, this could indicate a sickness, malnutrition, worms, or parasites like coccidiosis. If a bird has gained weight, it’s critical to ensure that you aren’t overfeeding them, especially with treats and snacks. Obesity-related complications can lead to serious health problems in geese. If you need to lower their food intake, you must do it gradually because a quick drop in nutrition could lead to serious health repercussions. In addition to weighing each bird, you should also pay attention to their body condition.  Does a bird feel thin with a prominent keel, but based on the number on the scale, they have not lost weight or have maybe even gained?  A loss in body condition without their actual weight going down could indicate a serious health issue such as abdominal fluid or a tumor. 

Check their poop

Goose droppings tend to be much runnier than chicken droppings, but like chicken droppings, goose droppings can look quite diverse. If they’re poorly formed, pasty, watery, strong smelling, black, bloody, yellow, neon green, or foamy, it could be a sign of parasites, illness, or improper nutrition. If you’re particularly concerned by a dropping, you can bring it into your veterinarian for a fecal float test for analysis, though you should consider fecal testing healthy-seeming birds once every three months to check for internal parasites.

Isolate if necessary

If you notice that a goose is unhealthy, it’s crucial to consult with a veterinarian and/ or compassionate care expert and prioritize accurately diagnosing the problem. Depending on the health concern, it may be necessary to isolate the goose in order to protect the rest of the flock from a potentially infectious disease. However, with some illness, such as pneumonia, often once a goose is showing symptoms, the other residents in the flock have already been exposed. In these instances, you will need to weigh what is in the best interest of all of your residents. A sick goose who is isolated from their flock may become more stressed, which could delay recovery.  However, if the goose is being bullied or cannot compete with the rest of the flock for food, or if you need to more closely monitor their food and water intake and fecal output, you may need to separate them at least temporarily.  You may find that keeping them in a quiet space with a calm goose companion is a good compromise until they are well enough to rejoin the flock.

If you find anything concerning, take a look at our Common Goose Health Issues page to help identify what may be amiss, but you should always discuss any potential health issues with a qualified avian veterinarian or expert.

Though it may seem like an overwhelming amount of factors to be aware of, once you’ve gotten to know a goose and what good goose health looks like, you’ll be an excellent goose health ally in no time!
