Ok. So my Dh wants to build us a coop this summer. We've never had chickens before. Is there an advantage to concrete foundation vs building it off the ground? He wants to build it on a concrete slab with a hinged panel in the back to lift up so it can be hosed/cleaned out to the outside. Most of what I have seen is folks building them off the ground. We do know we want about 10 chickens. I know that bigger isn't alway better, but in this case, (listening to everyone's chicken math, lol) is it possible to have too big of a coop for 10 chickens? We were thinking of building a 10x10 with an outdoor run. Do you let your chickens out on days with bad weather? Rain, snow, wind, etc. So many questions, I'll save the rest for when we get closer to actually getting our chicks. Thanks for any advice you can give me!!
