I have just come back from vacation (my husband has been home taking care of the birds) and one of my favorite roosters is very lethargic It just started today. He can stand but he doesn't move at all even when I go to pick him up. He is keeping his eyes closed. I separated him from the rest of the flock and put him in the emergency cage with food and water. He acted like he wanted to eat when I put the food in but seemed like he struggled. His poo looks normal and his crop is not swollen I literally have no clue what is going on with him but don't want to lose him and can not find a vet that will treat chickens. When I felt his crop he seemed like he wanted to get away from me but it is not swollen so I don't think it is sour crop.
