Every once in awhile when I go to close the coop door I'll notice that my barred rock rooster has one wing over a hen beside him on the perch. I'm not sure if it's always the same hen or different hens. Any thoughts on why a rooster may do this for a full grown hen? When he does it the hen is snuggled right up against him, clearly enjoying her status.
Incidentally, he's fairly good with new chicks, too. He hangs around the coop when they hatch instead of following the rest of the flock to free range. Yesterday the runt of this latest clutch was stranded and he came into the coop to see what the distressed peeping was about. He put himself between me and chick as he would put himself between me and a hen. He didn't seek to approach the chick but he did have an instinct to protect it rather than harm it.
I've also noticed that the broody hen does not make her angry sounds at him if he approaches the nest like she does when other hens approach it.
