Hello Anonymous, You must help your hens yourself. If you are not saving eggs to hatch, lock him up or get rid of him. The hens will be so much happier, healthier, maybe even lay more eggs. She is so submissive that he takes advantage of it. Other eggs may not be fertile if you wished to hatch them.
Nothing is wrong with either, just the random combination of birds.
Another hen or another cock might be much more compatible. This is a private posting area. A valid username and password combination is required to post messages to this discussion.
