im starting my coop tomorrow. the plan is to go with a 5' by 12' by 4' high. i was thinking of 2 feet off the ground. i have hread that the nest boxes should be up off the floor. how high should they be? would it be ok to have them stacked ontop of each other? is a 4' fence high enough to keep in chickens that have their wings clipped? im sure i have more questions i just forgot them.
