How do I know if my hens have CRD or something worse? Please Help.

Just to be clear, they will have to necropsy the bird, which means it will have to be euthanized.

My hubby called the Michigan State number and talked to a doctor there. He said Dittle Dumb had Cholora, we are to treat with Sulmet for three days then off a day, three days off a day, three days. So that's what we will do with the herd. Our Dittle Dumb died today and we are very sad, he was our first rooster. Anyway, thanks for the info and support. We really appreciate it!
