Lethargic Rooster

So for the past week, my rooster has been a lot more lethargic than usual. He is an 8-month-old buff orpington and he has always been really active. But now, he isn't as interested in food, just a single heascratch makes him fall asleep (which is a lot compared to before) and he has even fell asleep standing. It is also pretty obvious he is lethargic because at sunset time, he'd be the only chicken asleep among the flock.
His comb is still bright red and he looks otherwise healthy. Is this normal?

Is his poop normal? What do you normally feed him? Have you tried offering him other foods to tempt him? How is his weight? He should be gaining weight, not losing it. It would be a good idea to track his weight.

Is he the only cockerel? Do you have an older rooster in the flock?

His poop seems normal, and he has been eating the same food as all the other chickens. His weight seems fine, but it's a bit hard to tell from his feathers. I will keep track of his weight!
He isn't the only rooster though - in his small flock there is another older rooster however he is quite docile. We have others flocks though, with about 5 roosters totalling up in those (we will sell some soon).

I've also just noticed that when he sleeps, his head drooped.

The reason I suspected an older rooster is because, no matter how gentle they may be, they can intimidate a cockerel or younger rooster to the point that he feels he cannot eat all he needs to eat in the presence of the older bird.

I have a pair of older roosters, and even though they are both very docile, the younger one is always chased away from food, even though they each get their own dish of food. Your very young cockerel may not be getting enough to eat.

I suggest you separate him from the older rooster at least once a day so he can relax and eat all he needs.
