I am building some breeding pens and I need to keep them small and managable this year. I am thinking 4 x 2 coops for roosting with 4 x 15 yards. in this setup would two roos and three hens be ok? or would the roos kill each other. I could put just one roo in, but then I don't knwo what to do with the other. unless I just let him perma free range. would that be better? Any advice on setting up a small breeding program (for improving my flock and selling a few chicks) would be greatly appreciated!
