I agree that it definitely won't be big enough (the box said for 6) but it might be a scaled up version of the one you bought as they aren't having any problem with the ramp. It was all I could afford at the moment and I'm hoping it will do until I figure out which ones are roos and maybe have the confidence to build my own. Also the backyard is not overly huge especially with my bathtub garden beds. I really need to rearrange my yard. I've got the materials to build them a bit of a run but I'd like to free range them when their older. I felt it was extremely important to get them out of where they were. They've grown so much in just the last 3 days. It's crazy. The photo is so you can get an idea of how big the coop is next to a 5 year old girl.
It as you go.
