I am new to raising chickens and have 5 good egg layers right now. I have noticed something digging or trying to dig little holes under the edge of the coop to get inside. One time I saw a bunch of feathers all over. Can the bottom of the coop be covered with wire fencing to keep the little critters out? I am sort of thinking NOT, since the chickens could get their claws caught while scratching around. It is a small coop and 2 people can move it. Is their an easy way of keeping the little critters out?? Thanks for any help!
