@MrInappropriate @Maleve @ct_bergstrom The bigger farmers here keep their lambs in stables. If the flock grows too quickly and the youngsters are aggressive, the hunters come.
My neighbour said, if you have only one couple of corvids, this will chase the flocks of young males, protecting their territory.And it would be important, not to leave the afterbirth or carrion.He doesn't keep sheep for meat, so they are more resistant with fewer lambs and he is always at the place during birth.
