Hello everyone! I recently bought a Chickenguard automatic door opener and so far it's great and does everything I want. BUT how in the world do I block all the shavings that accumulate where the door comes down? I'm afraid it's going to prevent the door from closing all the way. So far, I've cleared all the shavings from door hole prior to the door closing. I want to enjoy this product and know that my girls are safe. My husband says he is done fooling with the coop so I'm on my own on this one. Lol. What do ya'll do to keep shavings at bay? Any ideas or suggestions?
