I am new to chickens & I started a small flock of 4 bantam hens back in October. Right after Christmas, one turned out to be a roo. In the few weeks he’s come of age, he’s over mated one of my hens to the point that only her down feathers are left over one of her wings. He is non-aggressive and a very good boy, but the girls are getting stressed. The issue is my setup is not big enough to add the hen to roo ratio needed to stop the over mating. At most, I would only have total six chickens. I don’t free range because I’m in the middle of the mountains with way too many predators. If I get him his own coop & set it up near the girls, will he be okay or is that cruel? I have been trying to rehome him over the past few days, but no one trustworthy so far. Thanks in advance.
