For about 2 weeks our birds have been coughing and a few sneezing and now they have snouty noses. I have lost 2. I am unsure what to do. I am very experienced with dairy goats but am clueless when it comes to chickens. We have cleaned the coop, changed the water, and cleaned the feeders. Goats are prone to pneumonia in this type of heat so I wondered if chickens would be also. Would Aureomycin crumbles be OK or should I try something else. I would read all the posts but I have 7 kids and I am a homeschooling mom and it is just faster to ask and get a quick answer. Thanks for your time and knowledge. Oh if is matters most of the birds are under a year and the Ameracaunas seem to be the worst affected, only one of the Wyandottes seems to be ill. Both birds I lost were 6 months old Americaunas.
