Show me your unattached nest boxes!

[LaurelC]

Modifying a duck pen to make an open-air type coop. Since the hens won't be locked up tightly at night, I don't need nest boxes in their coop. I currently have an old doghouse with a hinged roof that I'm putting a couple of plastic bins inside, but would like to build a nesting box that can be accessed from outside the run. Show me your pictures!
