I don't have any installed yet, but the one on our chicken shack is going to hinge down in the middle of the human door to make a ramp (to keep the ducks out, we hope), and the ones in the chicken condo are going to be on pulleys that slide up on the inside. The coop itself has a human door on the back and I'll have three separate pens with three separate doors. DH is trying to figure out how to make them work with the push of a button on a solenoid (because he's just that techy, lol) We'll see how they work once they're done. I plan to be able to pull the rope from the inside to open and close them without actually stepping into the individual coop spaces, but will only be separated from them by some chicken wire, so I'll be able to keep an eye on everyone and see what's going on, count heads at night and check food and water.
I'll have to share pics when we finally get to that stage.
