For someone interested in using one of these, some additional details would be helpful...such as the cost, the ease of assembling, any modifications you may have made and why. It would be nice to see an actual photograph of your coop!
I've seen these advertised, but never in actual use. How about some pictures of your set-up? That, and a few notes about what works best for you and what you may have had to adjust would be a big help to others considering this unit.
