I am refurbishing this old pen as an open-air coop (7'L x 6'W × 5H but with slanted roof). I'm in FL so the more air the better. I was looking for ideas, suggestions to add a nest box, after I make neccessary repairs of cource. I was thinking of building an exterior nest box to the left of the door (the door is the larger section on the right) since this is smaller pen. Don't want to go in if I dont have to. I'm planning to use this for bantam RIR. Would appreciate any design ideas.
