Does anyone have any experience with the Jumbo Fontana Chicken Barn by New Age Pets?
New Age Pet Fontana Chicken Coop
Prefab coops from almost anywhere are going to be much smaller than expected and nowhere close to housing as many hens as suggested on their packaging. Durability and longevity are also questionable in most cases. While I don't have personal experience with this particular coop, I'd look at as many options as possible before ordering.
For a similar price, you could probably build something more secure and larger to house more birds, or the same amount of birds more comfortably.
For a relatively easy to build option, I'd look at "Chicken Mobile Stage Coach"... (I have the plans but have not built one personally)
