This picture is of my DH holding a piece of wood where I want to hang the nestboxes. I wanted them 18 in. high and this is the height he is holding the wood. I should add that 18 in. is what the BOTTOM of the nest boxes will be at. He thinks that having the drop door directly under it will hamper them from being able to hop up and over into the coop. What do you think? Also, scroll down... This is the drop door and the angle it will be at. I do plan on putting "steps" on the board but our question is, will this angle be too steep? Will it be too steep especially with the design in the picture up above?
