well my dad and i built a chicken coop that is 8'x6'and 4' high. it is about 4' off the ground. I currently have 16 chicks in the coop right now is that enough room for all of them to roost when they are adult. My other question is being 4' off the ground do i need to build a ladder for them to walk up. I've heard that chickens hate to fly? also my chick are 4 weeks right now all i am feeding them is chick starter is that okay? do i need to give them grits?
