My Leghorn Rooster prefers to sleep in the rain. Don't ask me why. I have no idea why. He is 1 year old and refuses to go in the 3 coops that I have for my chickens. And there is PLENTY of room. He sleeps high on this platform that I have "re-constructed" just for him after finding out his weather of choice to sleep in. It's weird. I have tried putting him in the coops for weeks at a time and he makes a BIG FUSS and irritates the rest of the hens and roosters. He will not stop making noise until he GETS OUT. So, I let him out and he gets back on his platform, finds his spot and tucks in his head and goes to sleep. I have a wild turkey that sleeps next to him, so there are no hawk or owl predators that have tried to attack him.
