I am wanting to build a coop for my 10 chicks! They will all be layer hens so ideally I am wanting to make a coop big enough for 10 layer hens that will be safe, somewhat portable, easily accessible, and warm for our winters. I was looking at this coop and loved the design and idea: https://www.backyardchickens.com/web/viewblog.php?id=9413 I think this coop is a little too small for 10 hens so if anyone could help me with adjusted dimensions or how big it should be sq. feet wise that would help as well! Most of all....WHO BUILT THIS COOP???????????????
