Hi all.. I am wanting to start breeding 8 buff orpingtons. I have a a pen I built approx 4' X 12' to separate them from the rest of my flock. Is this big enough to breed all 8 hens? Will the rooster stay busy with all of them in there together, or should I put a couple hens in for a couple of days, and then switch them out with a couple of others? Also, these hens just started laying 2 weeks ago. Should I wait a little longer for the eggs to get a little bigger? Any additional info would help.. Thanks in advance!
