I had 5 RIR hens in with a RIR rooster for about 2 months collecting hatching eggs and about 3 weeks ago I sold the hens and kept the rooster to use for sexlinks later when my Doms are laying. The rooster is in the pen by himself now and every time I walk by he talks to me. My question is is he lonely or is it that my walking by stimulates him to be vocal. He sits up high in the pen where he can see the barnyard and other chickens. I let him out today.
