I am hoping to embark on chicken ownership in the near future. We have an existing old shed on our property which I think could be secured and modified into a coop (eventually w/ attached outdoor run), but I am hoping for some feedback on which modifications to make as well as the overall feasibility of this. Most of the wood shed-to-coop conversions I've found online have been in different circumstances (ex: the shed was moved to a new location, completely overhauled, etc...). This is a 10x12 wood shed, and we do not have any way to lift or move it in order to change anything underneath, so we would have to work with it as it stands now. It is slightly raised, but that appears to be only because the land underneath is inclined. Front of the shed is basically on the ground; the back has a few inches of space. Our property backs up to green-space, so we do have plenty of raccoons, coyotes, and small rodents we would need to keep out. My thoughts were that we could patch any areas of concern/holes, then install hardware cloth in a trench around the perimeter and secured to the shed. For the floor, I've been interested in the rubberized roof coating, but am not sure it can go on top of the floor as it exists now (see picture -- it's stable but oil-stained and maybe mildewy)? Should we consider re-doing the flooring entirely or is that really not necessary? For ventilation, I think we would install a hardware cloth door, framed just inside so the main doors would remain open. And then cut a space for a window(s) in the back wall. Input is much appreciated, especially if you have experience with a similar project.
