hello all, I have only three right now. I believe one of my chickens is a roo so I will be taking him out of the coop. My questios is can I add another chicken to the two that are staying. one is a RIR and the other is a Silver Laced Wyandotte. They are both about 20 weeks old. I am thinking of adding a opington which is allready laying eggs. My two girls have not started laying. Another question. When can I expect the RIR and the Wyandotte to start laying. Thanks for the help.
