We made a plywood brooder box. I want to line it with a tarp so that the tarp covers the bottom, comes up and over the sides walls of the brooder. I will clip the tarp along the top of the box so that it stays put, and then put the pine shavings down. I want to do this so that I can just lift up the whole tarp, bring it to the compost, and clean it off really well. Does this sound like a bad idea? Thanks in advance!!!
