I have an Over EZ coop and even though it seems to be made with quality materials, I
still had to add quite a bit of ventilation and modify roost bar placement. Over EZ is also guilty of fibbing on the numbers, as far as how many chickens it houses. I have the "large", which is 24 sq.ft, and they advertise it to fits up to 15 (my 8 pullets are fairly crowded in it at bedtime as it is)! Granted, as far as "prefabs" go, Over EZ is one of the better ones, but for as much as we spent ($2100), we could have bought a brand new shed, 3 times the size, and made modifications to that (I wish I had joined BYC BEFORE I ordered my coop, lol). It seems impossible to find an affordable prefab option that meets all of the "standard recommendations".
My husband is semi-handy and I'm completely useless as far as being able to build anything from scratch, which is why a pre-fab seemed like the way to go. However, thru this site and the knowledge/experience of so many others, I have learned that there are so MANY ways to offer appropriate housing for chickens (hoop coops being one of my faves)!
In the spring I'm planning to get more chicks, and thus, will be upgrading to a custom built 10x12 coop (I can't wait!), and I'll likely be building a "hoop coop" run extention. I'll be keeping the Over EZ for brooding chicks (which it should be perfect for)!
Here's my OverEZ (with modifications):
