This morning I went to let my two roosters out of their coop and I noticed that one of them was hunched over. His eyes kept closing and he seemed sleepy. I just came home to check on him at lunch and he’s still hunched. He just laid down on the ground and closed his eyes, but then he got back up. He keeps fluffing up his hackle feathers. I don’t see unusual droppings or blood but I put some Corid into their water this morning just in case it’s coccidiosis (my hen coop was recently infected but has recovered and the two flocks have no contact). His vent looks normal to me. I feel like he’s in pain but I don’t know how to tell what’s going on. Has anyone ever seen this? Edited to add that poop is normal as I just came back out and saw a dropping. He’s very interested in food also.
