I should add that I've faced this as well. For the NYD hatch, I hatched 4 welsummer chicks. (1 cockeral, 3 pullets) One of the pullets looks promising for breeding, and I debated with myself whether to keep her and get rid of the others, or not. A friend of ours wanted some girls, so we had homes for them. I went back and forth on whether to keep her or not. Our friend didn't want the cockeral, so I had the choice of integrating him with her. In the end, I decided to give her away with the other 2 girls - the boy will be going to the feed store - I will not integrate him by himself, he'll get the crud beat out of him by my hens.
