I have drawn plans for a 12 x 12 coop, two rooms, one for us to work in 6 x 12 and one for the chickens. I was thinking of putting the nesting boxes on the divider wall with an opening into the work/entry room at about counter top height for egg gathering. Would that be too high? Would I need a ramp? I was thinking I would put the roost across from the nesting boxes on the back or south wall with a similar height for the poop tray and the roosts above that by a foot or so. Does this sound like a good idea?
