I need to know what I can do to treat respiratory infection in my flock. I brought home two new chicks and thought they had been quarantined long enough. Now half of my chickens sound congested when they breathe, have runny noses, watery eyes and they’re sneezing. I’ve searched the forums and can’t find a concrete answer. We don’t have a vet around here that sees chickens. I’ve called all over. HELP!!!
