I am brand new to chickens ( in fact I don't even have any yet), and am wanting some advice on coop/run size. I am planning on buying a coop online as I need one that is attractive as to keep my neighbors happy. I am only planning on having 3 hens and the coop I am looking at measures 62" L X 32" W X 42" H. It says that is big enough for 4 hens. It seems small to me. Is this really big enough for 3 hens? Here is a link to the coop on Petco's website. http://www.petco.com/product/114699/Precision-Pet-Cape-Cod-Chicken-Coop-or-Rabbit-Hutch.aspx?CoreCat=OnSiteSearch#description-tab Any advice on this would be appreciated. One more bit of info. The reason I like this coop design is because it look like it would be easy to add extra length to the run area. Thoughts?
