Hey everyone, this is my first post on this forum. I'm getting ready to build my self a coop in the next couple weeks. I live in southern california and was wondering how critical it is to have the coop be fully enclosed. Considering the mild climate here I don't think it is necessary. Also I remember my grandparents coop when I was a kid. It was more of just a run with cover for rain and some nest boxes. Looking for suggestions. Thanks.
