My 1 year old Maremma pups have been guarding our lambs, goats, calves and chickens. There are 3 large owls living in the barn next to the house, and several hawks by day. Our 12 CornishX have had free run of the yard day and night and our 5 month and 7 week old layers free range by day. The dogs have run off the owls and hawks, treed a raccoon and discouraged a cougar all in one week. We haven't lost a single chicken all summer, since the dogs accepted them as their charges. Yesterday, the gate to the front was open. The littler chicks started heading out that way. There are cow dogs loose out there who could have slaughtered them. One of my LGD's trotted ahead of the chicks, and laid down in the open gate, blocking their exit. It was awesome. They guard from ground predators as well as those who fly. They follow the chicks around and remain close to them, not just chasing intruders. THIS is what Livestock Guardians do. It's a step beyond protection.
