Question for those that keep back up roosters for breeding. Do you keep the back up by their self? If so are they far away from the girls or is the pen right next to the girls pen? How big is the pen or how big should it be. Not sure I'll have enough for a batchelor pen and while I've had very good luck with roosters getting along (even with removing from and placing back into the flocks) i know there will come a time when that norm for me will change. I just want to be prepared for if I need to keep the back ups separate.
