Glad you were able to get more information from A&M.My one chicken Luna is responding to Mycoplasma treatment. The poultry director at Texas A&M said I can vaccinate new birds. It’s ubiquitous and treat any with symptoms. No need to cull birds.
As far as the necropsy for my polish Mazzy. Quite interesting. She only had 1 kidney and that kidney failed. She had urates in her joints, trachea etc. He said she was coming into reproductive age and the change in hormones and extra calcium was too much for her enlarged kidney :-( glad to have an answer. I’m also sad because I’ve lost 3 polish- I think poor genetics.
I'm sorry about the Polish, but it was good to find out that information as well. Very interesting to say the least.
Thank you for the update.
