I got the smaller version of the coop, the 4x4, this July. Its plenty for my three girls. The things I really like about it are:
1) Very easy to clean. The floor is easy to wipe down and everything is easily reached.
2) The girls love the space underneath and hang out down there on hot, sunny days.
3) The window opens and closes easily and has a gate across it to keep out unwanted intruders.
4) Its very secure. When the girls are closed up inside they are perfectly safe.
As we aproach the cold weather though, we've realized some adjustments are needed. Its not insulated so we will be adding that this weekend. We will also need to create additional air flow as when the pop door, back vent, and windows are closed there really is no air circulation.
We got ours at Martin's Garden Center in Tyrone for $625 and then paid an additional $50 for them to deliver it to State College and set it up where we wanted it. As I recall, they wanted $780 for the 4x6 version.
There are two versions-- metal roof and shingled roof. The metal roof version has better circulation than the shingled roof as it has an overhang.
