Tracy, The screws just started coming loose on mine. I used a "special" treated flooring material that looked like pressed wood chips. So much for that holding up!! Can't find 10 inch wide rough cedar around here. Do you think 3/4 inch treaded plywood would work? Will the "treatment" hurt the birds or keep them from nesting in them? Never thought about how many times a wood duck flies in and out at full speed in that box!! Could take its toll on the material I use. I'm ready to build another one. Need a little advise.....anyone?

Dear Alcohol, We had a deal where you would make me funnier, smarter, and a better dancer... I saw the video... We need to talk.
