I hired a guy to build me a coop based on pictures of one he built that I liked. I told him I needed one big enough for 10-12 hens. I'm new to all of this and he builds coops, and has chickens himself. The coop interior is 4x4 with exterior nesting boxes and an attached 8x4 run. Now that I've done more research, I realize this is no where enough space for that many birds. I will free range them as much as possible but I know there is bad weather and other factors that may affect that. He delivered the coop today and I'm hoping you all can help me figure out how I should have him enlarge it. I'm not a builder by any stretch of the imagination, so I have no idea what's possible. I have 10 chicks being delivered Jan 12th, so I'm definitely going to need to room in a couple of months. I plan to attach another run to what's included in the coop structure, but I'm open to all ideas. Help!
