Well I like the fact that mine has lots of windows, in fact the coop that Im talking about I bought per made and it had a long door that would flip down so I could reach in and get the eggs right out of the nest. But I found that I liked walking in to the coop so I could check on every thing and anyone that was inside much more then just sticking my hand in and being done so I covered that opening with wire and now it is a long window that I can close and open when I want to, this also allows me to see if anyone is in a nest, or if any eggs are in there that need to be collected, if so I walk in and then I can see if they need any feed or if the bedding needs to changed, stuff like that. Oh and the fact that I can hang the feeder and waterers is really nice, I also added a perch in front of the nest boxes to help my girls, they seem to like it better. I put the roost at different levels b/c some of my birds like to be lower like the heavy girls but my bantams like to be as high as they can, this keeps everyone happy.
