The coop is tall enough to walk in and is 8 ft by 4 ft with 3 nesting boxes sticking out the back. We like the lay out because we can pick it up with the skidster and rotate it from place to place. We went from 6 chickens to 12 and the coop feels WAY too small. The coop is currently not fit for all of those girls and they struggle to find comfortable roosts. (I know that needs updated badly) Could adding a second layer of flooring count as adding square footage for our growing flock? We may end up having up to 20 hens if my habit keeps up! I truly want to scrap the whole thing and start over, but I am afraid my boyfriend will leave me if I do. He has made it very clear he doesn't want to spend anymore time on the coop, so it's all on me! UPDATE: Ideas for building a new coop or renovating with existing materials on the farm: Pallets, fence posts, old cedar, tin scraps, metal scraps, old tires of various sizes, different types of fencing and so much more! I love the beautiful coops everyone has , but am working to make this habit as CHEAP as possible (i.e. we only buy chickens and feed) Help is greatly appreciated!!
