We're first time chicken owners and have (had) three hens and one rooster. We got them last October and the girls began laying in February. About two weeks ago we began to notice that one of the hens wasn't very chatty and her comb started to fade from a bright red to a very light pink. She died yesterday. None of the hens has laid an egg in over a week. We haven't heard the rooster crow in over a week. The three surviving birds are very lethargic and now the rooster has black spots on his face. They're hardly eating or drinking. Their poop looks normal. I just snapped a picture but can't figure out how to attach it to this message. Please help me -- what's wrong???!!! Thank you.
