OK, didn't break the camera, I think.
This shows the front of the box. You can see the two spring latches, one on each side.
This is still the front of the box, but with the front open and down.
This is a close up of what the top edges look like. The sharp cut edge is folded inward so the surface the doe jumps over to get in the box is smooth. Also the cardboard edge slides into the opening so the doe can't easily get to the top edge of the cardboard... holds the cardboard in place. This folded edge goes all the way around the top.
When the doe is through with the nest, drop down the front and slide your cardboard and nesting material out and into the trash! Hose the box down, scrub with a cleaner/disinfectant and put it away until the next time you need a nest box.
Let me know if you have any questions. Love chatting buns with you.
