We are getting ready to build our first coop. We are gonna build it 8' x 8'. We plan on free ranging but closing them up at night. How many nesting boxes do you need for about 8-10 hens? How big do the nesting boxes need to be? How high off the ground do they need to be? The roosting posts need to be how high off the ground ? How much room per chicken on the roost? How far from the wall does the roosting pole need to be? Could I put 2 roosting poles across the 8' wall? If so would you put one like 12" from the wall and the second pole like 24" from wall.? Lots of questions.
