I would like to add some bantams - specifically d'uccles to my flock but I'm not sure if the rooster might hurt them. I will have 10 standard size hens and 1 standard rooster. I'd like to add about 4 of the bantams. My rooster is an EE. My concerns are 1. He might hurt them trying to mate and 2. Ten standard hens to a juvenille rooster won't be enough if he can't mate with the bantams. Thoughts?
