Well I got a couple Brahma chicks for my husband from a breeder, something I promised myself I would never do. Turns out they have coryza. I have kept them in a strict quarantine. FAR AWAY from my healthy flock. Never again will I bring a live chicken, only hatching eggs as I promised myself. Now I'm guessing I should cull? Would goat hoof trimmers work to do the deed? My husband is going to be so upset, I bought these as a way to include him in the hobby and it has turned out to be a nightmare. And I paid good money for these sick baby's.
