My friend started out with 7 chicks. He lost 4 of them to hawks. After he solved this problem by putting netting over the run, now racoons are eating their poor little feet . One of them has already lost a toe, and can wlk fine, but the other looks like she is starting to loose a toe and limps around. Can racoons really pull a whole toe off? He has wire mesh for the bottom. What can he do to deter them away? They have ripped though the wire he put up around the bottom of the coop.
