Yesterday my rooster flew out of the coop, I am not sure how long he was out but when I found him he was hiding and kinda cowered down. So I picked him up and put him back in w the others and he started eating and seemed fine. I just found him in the coop and his face was swollen, under his chin. Then I was feeling him and I realized his whole body is swollen. Face, neck, tummy... everything. I dont know what to do. I have him in my bathroom and he is seperated from all my chickens. Nobody is sick... could he have been bit by something? I am in an urban neighborhood so maybe a spider or bee? he is sluggish and not eating.
