I am fairly new to chicken keeping. I started out with 6 white leghorns. I recently added a red sex link that a friend gave to me. I am thinking of adding 2 barred rocks to my flock. How well do barred rocks do with white leghorns & sexlinks? I don't want my flock to get bullied. My flock is 17-20 weeks old the 2 barred rocks that i am adding are 15 weeks old. I've read barred rocks can be bullies but they are my favorite looking chicken. So I really want a couple in my flock.
