I wanted my girls to have more room so I had my handy DH build what I call a "porch" so they will be able to scratch in the dirt and feel like they are more outside. It's small but I think this will do the trick. I'm going to add a mix of good dirt in there. In our backyard, we had originally remodel the garden shed 12 ft L X 4 ft W as a coop/run. It has a concrete floor with 2" pine shavings and I've wanted to give the chickens a chance to scratch in the dirt like chickens love to do. Before After...not finished yet More pics to come.....putting finishing touches on and adding a good mix of rich dirt for them.
