My 18 1/2 week old cockerel is being a little rough on my girls I think. He keeps grabbing them and trying to mate with them but they want nothing to do with it as they are only 14.5 and 12.5 weeks of age and are not sexually mature. Should I maybe seperate him at night/day when they are cooped up and let him interact with them when I let them out for a few hours each evening or should I just let nature do its thing. I am trying to keep the girls as stress free as possible in hopes of early layers. They have been together for 2.5 weeks now and the pecking order has pretty much been established in first couple of day. He is good with them for most part, just if one comes close enough and isnt paying attention then he tries to mate. Suggestions please
