Since allowing our hens to free range resulted in a hawk getting a free chicken dinner, we now keep our girls locked up tight. Chickens are very industrious and will turn their yard into dry bare dirt in no time. I wanted to encourage more biological activity (aka bugs and stuff). So we’ve put in some 2.x 4s topped with wire. Separating the chickens from the ground will build the soil instead of letting it erode. Underneath is compost and grass seed. It’s starting to come up nicely and the girls are keeping it freshly trimmed and fertilized. On the lower level, we’ve added oak leaf mulch (which is abundant around here), to create a nice deep litter level. I tossed some diatomaceous earth and ashes in with the dirt in the corners where they like to take a dust bath to help with mites and fleas. Happy hens lay delicious eggs!
