For chicken coop maybe. Patio stones around the edge of the fence makes it hard to dig under. Great idea for the outside of chicken coops and garden fencing too. Would also keep weeds from growing up into the fence.
They say "doghouse", but I see "chicken coop". Lol "What a great dog house. Can go inside if they want, or out on the porch if they want and still contained without having to be on a chain. Plus no mud when it rains.
