OK... my first illness in my flock so this is all new to me... one of my 6mo old roosters I hatched from an egg became lethargic two days ago and I noticed a black discharge on his beak... he has gotten much worse today and there is a whitish film on his eyes. I have been searching for info and I think that it is possibly infectious bronchitis? I am going to go to the feed store ans pick up an antibiotic... no one else seems to be ill??? any thoughts, advice, warnings would be appreciated.
