This isn't used for my chickens but I now have some very, very happy quail. They act like completely different birds verses being in a small wire cage. We built this where my brooder was (red box in the middle) under an existing tin roof. The wife and I finished it yesterday. We plan on adding some more ground cover but not sure what, so any suggestions would be great. Anyway here is a 12 x 24ft quail pen with electric fence on the outside in hopes to keep out any predators.
