Recently new to chickens, I had a vet come and inspect the farm and all the chickens. She found them all to be in good health and my farm to be clean and in order. She also advised me on normal worming, parasites, chicken health, etc. Later that week, one of our favorites died suddenly. No symptoms, just dead. As recommended, I brought the carcass to UK for autopsy. A week later another died without any symptoms and again, I brought to UK as advised. Then wormed with safe guard as per vet, and the few people I asked said "some chickens just die." When autopsy results came in, they found gape worm, mycoplasma gallisepticum, mycoplasma synoviae. Since then I have heard widely varying opinions on mycoplasma. The vet said it was fairly common, NOT covered by NPIP testing, nothing to indicate eradication of the flock, can still eat eggs and meat. Others have said to cull everything, apply severe cleaning to everything including clothes and boots and the ground and cold wait period until attempting to start over. Double fencing is advised if attempting to start over because this could have come from the wild turkey that frequent my farm, or even visitors. I’m not showing my birds but I did want to NPIP and sell eggs and chickens. Many people sell MG birds and many people never know their birds have it. You would need to specifically order MG/MS tested negative birds to start fresh and even then the turkey visiting the farm could give it to them. There were never any symptoms in the birds so I have to assume the entire farm is infected, and have begun an aggressive antibiotic treatment plan. (Still won't cure it, but will stop further death.) I would feel bad selling sick birds, but once they are better, could I sell them? Try to hatch? Sell eggs for hatching? I could test every chicken on the farm for big$$$$$ but chances are they are all infected. They will always be a carrier, but most people don’t test and don’t know if they have a Mycoplasma+ bird/egg, but now assuming I do, what can I do?
