NICE, NICE COOP !!! Love the way it all blends. Looks great. Bet your girls will be happy...along with their roo. We just finished a second one that's on the same idea as yours but our door is on the high....6 ft...end and windows on each side...back , 4ft high is solid. All of our eaves are ventilation too that can be closed in severe weather.
Happy wintering.
