Ok i have a small coop and i want to expand my flock, my run is 23 feet long by 12 wide. I CANT tear down what i have already to build a bigger coop but i have the material for another small coop. My question is should i add it on to the current coop or just put the other coop next to it ( which is what i really want to do). This second coop im planning would be a roost only and leave the old coop with its roost but with the nesting box still in it. Or do i need a roosting box in the NEW one as well?
