Since July we have been battling with a respiratory disease among our flock. Granted, this is my FFA project that was started in March, and while I may have thought I had enough previous knowledge to raise a strictly "non-GMO flock", obviously there was a lot to learn, and maybe my approach of "no probiotics, antibiotics, vaccines, or anything other than non-medicated feed and water may be given to them" was a little much. But what's done is done and now I am left with a disease that keeps coming back and a flock that is obviously infected. We have tried medication (Tylan 50), Safeguard Goat Wormer, Antibiotics, Oxytetracycline, among other things trying to cure our flock. Yet, here we are, four months into trying to cure them, and failing miserably. We have come to conclusion that if we do indeed want a healthy and productive flock, it will be best to cull our current flock of 30 birds and start over again at the end of December. I read that you should report any poultry respiratory disease to the USDA, is this true? And will it be beneficial to me? We really want to know how to ensure that we completely clean our coop and get rid of the disease. We live in West Michigan, so it is very cold now. If we do call and report, will they give feedback on how to ensure a disease free coop?
