I have a very dominant hen who will not let my rooster breed. Every time he tries to do his thing, this hen chases him off. She wasn't like this before with my other rooster. She just hates this one. I am considering artificially insemination of my rooster to at least 3 of my hens and have a video from a breeder on YouTube who shows how to do it. Talked to a couple of vets about the proper size collection thing for the rooster. Anyone else ever tried this? I went out one day and checked all of my hens to make sure I totally understood their parts and the rooster just watched. He doesn't know it, but he will be coming into the house soon along with the hens and I am going to do what I have to do to get him to "work". If you have tried this, please let me know how things went. Thanks.
