is this an issue anyone has. We are planning to build our coop out of OSB. We have a cement patio block (you know, those big square ones) that we are planning to use as a base. I think we need a floor too, to keep mice out since they can get between the patio blocks if they want to. My husband doesn't feel that using wood as a floor would work since the mice could chew through it. I also want to put vinyl flooring on the floor for easier clean up. I think that the mice would not be likely to bother for the most part. I am being told by my husband and his dad that I an nuts to think so. We really do have a problem with mice around us so, maybe I should just forget it. I am really getting frustrated. Every time I think of a solution somebody shoots it down.
