I got a rooster, about six months old, three weeks ago. He's been working on both my hens, although one of them successfully avoids him all the time. The two hens are not even close in age or size. One hen (white) has been laying constantly, the other one (a black banty-type) only laid one egg, and that was before the rooster arrived. The last three days, the rooster has been nesting in the house, in one particular box. He stays in there for about an hour. Today, in that box, was a small egg. I never saw the black hen in the box, ever. She never hangs around the house, and the one egg she laid was outside on the bare ground, no little hole or under a bush or any type of nesting behavior. My question is, and don't laugh.... can roosters be both a boy and a girl, like hermaphrodites? Could he have somehow laid an egg? Hey. I can tell you're laughing. But seriously, has this ever happened?
