Hi! There is a person who sells coop plans on ebay called "playhouse coops". I see that some of you have a coop with this design. It is cute. Here are some links to the coop I'm talking about: https://www.backyardchickens.com/coops/playhouse-coop.html I'm thinking I'd like to get 3 full size orpington hens. Would that style of coop be too small for them? The coop + run looks like a good size, but the actual inside part seems small? Or would it be ok? Maybe this coop is better for bantams? If so, where can I find orpington bantams? Also, I live in Upstate NY. Would I need to insulate it? Looks like it might be a little small inside to fit insulation? Thanks!
