It’s all important, but some things are life-or-death important. If you have a chicken with a known allergy or who has a heart issue that makes them stress easily with restraint, you must make sure that information is not only documented, but documented in a way that ensures anyone working with that individuals knows and is constantly reminded of that information.
If incoming residents came from out-of-state, it is imperative that you have the proper documentation- typically a Certificate of Veterinary Inspection (CVI) as well as testing for avian influenza and/ or salmonella pullorum. Be sure to keep these test results on hand in case you need them in the future. If one of your residents becomes ill following the arrival of new birds, and avian influenza is suspected, you need to be able to prove that the appropriate testing was completed.
