With our current coop the hens roost on the nest boxes even though we have roost poles up. I am currently designing a new hen house and trying to figure out how to prevent this from happening. I have ideas but they are to complicated for what I want. This hen house will be 10 x 10ft and have 2 rows of 10 nest boxes one on top of the other. How can I make sure they prefer the roost polls to the next boxes?
