Pros: Easy to clean, and The Girls love it!
We were originally going to build our own boxes, but as we neared the end of our coop build, we decided we'd had enough hammering for one lifetime. Went to Del's and bought 2 of these, and I'm really glad I did. They're easy to clean, the sloped roof keeps the birds from roosting/pooping on it, and all the chickens have been happy to use it. I was afraid my Girls would be too big to use it, but even my brahma fits in nicely. I'm cheap by nature, and I built my coop with lots of reclaimed/repurposed items, but I'm really glad I dropped money on these nest boxes.
