So we went and got the starts of building the frame of our duck/goose house. We're using pallets for all sides, stuffing them with R13 insulation, and completely covering them with plywood which will then be painted. We're even going to have a little screened in porch (the foundation pallet is a 4x10) where we'll keep there water/food and it will be locked up. I have concerns about what to put on the flooring INSIDE the coop though. The porch will just be decking with a water proof underlay, that way any water or mess can just drain through and out. I was thinking about laying down vinyl flooring on the inside for the ease of clean up...just shovel out and spray it down. Anyone else have any better suggestions??
