Hello All, I have about 15 Black Jersey Giants right now and I love them. They lay enough eggs for my family to eat and give away plenty. They are big and yummy when harvested for meat. And they never attack my kids. But, they never get broody. So I am wondering about mixing in another breed known for broodiness and generally similar in these other BJG trait we already love. We live near Buffalo NY so winters are cold. They free range quite a bit. Would Cochins be good to mix in here? Wyandottes? Or is breed mixing unwise and to be avoided? I appreciate the thoughts and comments of all the veteran chicken farmers out there. My goal is a self sustaining flock that produces eggs, meat, and young without electricity.
