best of luck on your homesteading adventures - and on your goals here. i've just started following you & hope to learn and share ideas together!

i love that you're wanting the coop to match the raised beds!! i have had a couple of different beds, in different places - i recommend doing some landscape fabrics on the very bottom, with whatever else you have that will eventually break down. i've done layers of thicker cardboard, i've used OLD 100% cotton towels, and i've used nothing. with nothing, i always get bindweed a few weeks later. those little buggers are tough!!!!
