Yes he is eating and drinking I'll be honest I don't know what to look for when it comes to a crop I'm knew she could you help me on what I should feel for or whatever cuz I don't know what to look forLooking fine to me, that looks more of a dark red. If he was falling right to left that may be a issue, is there any other symptoms? Id seperate him from the other chickens though. theres many things you should try,
maybe gently massage his crop a bit. Is he eating/drinking well?
