I am in the final stages of setting up my coop. Don't have pictures yet but soon. My challenge now is dropping board or no dropping board. I understand how easy they make cleaning but space is a big issue here. My coop is 4' x4' and about 6 feet tall. The nest box is mounted partly outside to allow for more space inside. I'm only going to have 4 hens so I should have enough coop room for the ladies. I have a ladder from a bunk bed to use for roosting but thought I would mount one more roost higher for the girls, about 4 feet or more. How wide does the board need to be to catch the droppings? I don't know if chickens are projectile poopers like I know birds of prey are. Any help will be appreciated. Alice in Chickenland.
