My husband just installed an automatic pop hole door using an antenna. It works fine, but Melina, our "special" silky bantam, doesn't perch with the other chickens. She perches right in the pop hole doorway! I have to go out every night and shoo her inside when the door is about to close. I am afraid it will close on her, and she is so little, and the door is made of thick plywood! Anyone have any advice? Thanks, Debra B.
