I have many breeds of chicks, now 5-5-1/2 weeks old. I'm thinking I may be a little cockerel heavy but since so many breeds and my very first time with chicks, I'm not so sure how to identify by the combs. When chicks do the stand off with the head bobbing, is this strictly male behavior or will pullets do this too to determine pecking order? I also have chicks that hop up and down while staring at each other (this is a hoot).
