I have two roosters about seven years old. The bigger, more dominant one has been just sleeping all day either standing or laying down. Crows very little. He free ranges all day with the others rooster and hens. The two roosters and some of the hens sleep inside the house but the two roosters have their own separate room. Haven't seen worms nor blood in his stool. No mites or lice. No wounds. Crop is mostly empty since he hasn't eaten much today. No running nose or sneezing. It's very warm here in Florida still. Any ideas?
