I came out to feed the chickens this morning and noticed my rooster was laying down, which is highly uncommon especially at feeding time. I check him out and he can barly hold his head up. I tried to make him stand on his feet, and he's unbalanced and lethargic acting. I fed him water, made him drink a few drinks, then I noticed he had pooped bright green. Which is uncommon for him. Any suggestions on what could be wrong with him??
