I was so frustrated with having to wake at 5 in the morning to let the chickens out, I began to think, like genious minds do, of a door that would be predator proof and simple. I know that there are motorized doors on timers, but from what I can see they are very expensive . i thought about making a hole in my METAL wall above the height raccoons and possums can reach. i will put a plank in the hole to alow the chickens to fly to the door "hole". they can fly out in the morning, and fly in at night. predators can't reach the door because they can't climb a metal wall. I hope ?this is what i came up with... will it work? do you think it is a good idea? will you try it? thanks in advance for your replies!
