3) Update: The guy from the Chicken fountain emailed me yesterday after seeing this review. He seems genuinely horrified that he missed my email telling him the problem was unresolved. He sent me a prepaid shipping label and says he'll refund my money, including shipping, when I return the unit. He also offered a replacement, but I've already bought something else and I can't return it. So I can't comment on the durability of the product, but I can at least now say he stands behind it. I really do wish this had worked, because I prefer the slim design and how little room it takes up. If I ever lose my mind and get a second coop, maybe I'll try another one.
