I built this chicken coop for my four grandsons ages 6 thru 13 so they could gather eggs, water and feed without having to go inside of the coop. On the right side I built individual nesting boxes so they could retrieve the eggs without letting the chickens out (which 6-year-olds are prone to doing) and on the left side rear are the two outside feed boxes that keep the inside feeders full and the automatic waterer so they don't have to continually fill the regular round water troughs. Another larger door on the left side is opened once a month so they can all clean out the coop. A ramp and door are on the front for the chickens to come and go. Sorry, but one picture can't show all the amenities. Have not finished the steps leading up to the porch. I don't know if this qualifies as "Green" but the boys sure love it.
