Over the winter there's been something digging tunnels around the coop. I have a 2 ft hardware cloth apron all around the perimeter of the coop but it was able to dig itself inside even after all my efforts to block the tunnels. I thought it was mice but none of the mice traps worked, not even the peanut butter over the bucket trap. Finally my son was able to trap 2 little rodents but they're not mice. Are these shrews???
