I have this very well built 4 x 6 coop for sale. Made of 2x4 construction with smart board siding, painted interior and insulated walls, it has 5 nestboxes with external egg doors, a brand new window, and under eave ventilation with hardware cloth over all openings. Both front doors open for ease of cleaning, and there is a removeable hardware cloth "screen door" for the right door so that the door can be left completely open when the weather is warmer.
