It looks perfectly adequate to me, good price too, the feedback seems to be good on the chicken coop. I have read a few posts on various sites that have said about the quality of some of the coops being sold on ebay, but this one looks ok.
We tend to recycle what we have and what other people don't want to build coops - garden sheds, recycled wood, have some pretty good ones and have not paid very much at all.
Never had one with a metal floor so can't comment on that, although it looks like a good idea, she says going on the hunt for metal for her next project
