My 5 month old Salmon Faverolle cockerel has not been doing well the last couple of days. Two days ago I noticed he was outside very little and sitting down most of the time. Yesterday he didn't go out at all. His comb is very pale also. I noticed 2 days ago that his poo was greenish yellow on his bottom and not solid. I was just looking at the other post about the "sleepy hen" and now I'm thinking it sounds similar. Are worms a possibility is a chicken so young? When I checked him this morning he was sitting and didn't get up. Help, any advice would be apreciated. Jen
