He does have room. He is fairly high in the pecking order, too. He is protective of the coop - if he is near when I go in to get eggs, he will try to attack me and he stands guard for some of the girls while they lay. I did end up going out and moving him so that momma could go back on her eggs...
Okay, so I know he's not actually broody, but can a rooster keep eggs warm enough throughout the night? My hen just started sitting on eggs, but I have a rooster who always sleeps in the nesting box where most of the hens like to lay. He kicked the hen out tonight and is sitting on the eggs...
