Hi Folks, I am just getting so excited about getting chickens, and it's been great to find this forum, as it has tons of info that I have been looking for. My coop is a slant roof 6'x8', that is sitting on treated 4'x4''s which are in turn sitting on cement blocks. I figured this height would prevent rats from creating a nest under the flooring. After reading about chickens laying eggs under the coop on one of the threads, I think I may have to put chicken wire around the bottoms to keep the chickens out, from under it. The floor is plywood now, but I got to thinking that if I screwed some galvanized metal on it, and bent it up an inch or so around the perimeter of the walls, it would be water tight, (so plywood doesn't rot) rat proof, and easy to clean/scrape. After scraping out the litter I could gently hose it down, and squeegee the water out the door. (I guess this will entail a lift out sill board) Now I haven't seen a thread about using this type of flooring, and wondered if I was the first to think of it, or can it cause problems for the birds? I doubt they could eat the galvanizing, unless they did some pretty serious scratching. What do you think?
