Hi all. So I have a beautiful RIR mix rooster named Harvey. He’s a great roo. Gorgeous, very polite, never attacked anyone, protective, and quite gentle with the hens. I had him separated for a couple of weeks while my hens were molting and also while I introduced two older 4-year-old hens to the flock. I now have five hens. One lavender Orpington, one golden laced Wyandotte, one RIR, one partridge olive egger, and one red Sexlink. Now, the olive egger is a very small girl. Quite skittish. She probably weighs around 3 pounds. She isn’t a bantam, just petite. The rest of the hens probably weigh around 5-6 pounds. Now, the rooster is easily around 10-15 pounds. He doesn’t mate with them too often but had difficulty getting his balance when he does. We keep his spurs and nails short and we keep him separate three days a week so the hens can get a break. But I’m a bit worried about the olive egger. Will him mating with her hurt her back? Will him mating hurt the other hens’ backs? Also, considering we got two older hens and the rooster is about one year old, prime of his life and all. I suppose my question would be, even with keeping him separate a couple of days a week, will it be too physically and psychologically stressful for the hens (particularly the older one and the olive egger)? Thanks in advance for any replies and sorry for the lengthy post.
