I'm finishing my coop tomorrow! Time for the chicks to move out of my bedroom (the only dog-free room in the house.) One question I have before I move the girls in, does the ramp look good to you? I think the slope is probably fine, but I am worried that the opening isn't big enough. I've got some good sized breeds -- Cinnamon Queen, Delaware, Easter Egger and Salmon Faverolle. Thoughts?
