We have the motor to get our automatic door up and running, our only concern is how secure the actual door is. Right now our coop is bomb proof to keep predators out and we are worried that with no real way to "lock" the door raccoons might get in. Our neighbor has a set up with a deep lip along the bottom, so there is no way to get under the door and lift it, but it seems that they could push and lift to get in. I would love thoughts, ideas, pictures! I am really itching to get this set up for weekend getaways!
