For some reason my daughter in law was asking about MG. She is thinking that we may have to destroy the chickens in the coop. They are not showing any signs like the runny nose or crusty eyes or whatever. We did just culled a rooster and a hen because they were sneezing and coughing with a clear discharge from the roosters nose. The others seem fine...they are eating and moving around. Are there any other signs? I did read that it is usually found in chicken farms but I would like to know for sure. We dont have the funds to have tests done or anything.....I would appreciate you alls help....thanks guys
