Neat coop. My Dad made a similar one when I was a kid. Only it didn’t have the window vents. That’s neat. We had one row of laying boxes on one end with a small door on either side to reach in and gather the eggs as well as a front door for the chickens to walk down the ramp to the penned in area. We had a 1/2 dozen bantum hens, a bantum rooster and one rhode island red hen. Sometimes we let them run loose and they loved roaming our large back yard. One year we let the hens set on some eggs and we ended up with another 1/2 dozen bantum hens and one 1/2 bantum/rhode island red rooster, who grew up to be quite beautifully colored with various shades of red, white, and teal feathers. We probably had them about three years and then my Dad gave them to his Dad to replenish his coop. I will have to share your design with my son who is thinking about raising some some chickens.
