Hi...I posted about an hour and a half to two hours ago and have not seen an answer yet so someone must be doing some research in order to answer my question. (That or I'm so tech challenged that I failed to complete the post;-) my question was...is there any good reason NOT to build a coop with a concrete floor? We live in the Pacific North west and it can get very wet here. My concern about concrete is related to dampness and cold. We don't get too cold generally at our location but it has been known to get in the lower teens a few times. I have ordered my chicks and my husband is anxious to get started on the coop. The concrete is his idea but we both would like some confer at ion that it would be workable....thanks again.
