I have another sick chicken, He is a year old rooster. The past few days, he has not been himself. Today he has been laying down most of the day with his eyes close. He will get up and walk around some, but not much., His crop is empty. I don’t think he has eaten or drank much today. His poops are a strange bright green. We put him with the hens; He has not really even tried to mount the any of them. (He is NEVER with the hens!) He seems sleepy! What should I do? I will try to post pictures soon.
