Bleach out your water dishes!!!!!!!!!!!!!!!!!!!!!!!!! Look in your chicken's mouths and if there is cottage cheese stinky stuff it has started. They say copper sulfate is a preventitive and will help cure it. If they have it already Flagly (fish zole) will also help cure it. They get it from Dove, pigeon salivia from the water source. I just found all this out. AUGH. My poor main rooster is going through a hell of a time. Still waiting on the flagly.
