I have an 8x8 foot area, I want to put the nest boxes and roosts on one side and let them have the other side as their run side. Should I elevate their nesting area, to give them more room on the floor for the run area? Or is ok to have just one big open space for their nests and their run and feed area? Hope that makes sense. In addition they will be let out in the yard when I'm in the backyard too, when they can be supervised.
