how big would the coop need to be and the run space too? Would 4x4 coop and 6x4 run work??? My dilemma is I have too many roosters but I have raised them since babies and I am attached to them. I don't want to kill or get rid of them. I figured I'd build some extra pens so they won't fight. Be still be able to be with the flock, only divided. Do you think this will work????
