My rooster (Copper Maran) seems to favor one hen (Golden Comet) in particular. He still "services" the other girls but always goes back to the one to "hang with". Recently she's gone broody, and I'm allowing her to hatch some babies for me. So, needless to say she spends most of her time in her nest. I noticed this evening, when everyone is going to bed, that he laid down in front of her nest and purred at her for quite a while. Is it possible for a rooster to have a favorite? This hen seems the most dominant of all the hens. She puffs herself up and even goes after my dogs if they get too close to the rest of the flock.
