We had one as a starter pen for 7 full sized birds. They had a run like in the pictures as well. It was way too crowded for them by the time they were 6 weeks old. So we built a Chicken tractor and sold the hutch. By the time we sold it we had reinforced it several times. We had wheels on the bottom so I could move it easily(tractor style) and it didn't hold up to the stress very well. It also blew over in a good wind once while the chicks were inside and we had to start anchoring the base. I thought it was pretty expensive for the pain it ended up causing.
