From the coops I have seen, and even the design I plan to use, the nesting boxes are always seperated from the roosts. However, I want to put my roosts over my nesting boxes. I plan on building a row of nesting boxes low and putting a poop shelf on top of the row of nesting boxes or just above them that will hold pans of Sweet PDZ. Then I want to put the roosts higher up over the poop pans. My coop will have a bump out for the nesting boxes so I can access them from outside. I figure if I have the poop pans just over the nexting boxes, I can build the access door to open a little higher. That will allow me to access the nesting boxes and also remove the pans for cleaning with only one exterior hatch opening rather then a nesting box oopening AND a poop pan clean out opening. The nesting boxes will be protected from poop from the roosts by the poop pan between them. Does this make sense? Is there any reason why I shouldn't do this?
