@MrInappropriate @Maleve @ct_bergstrom Living in a region with sheep farming, I understand you completely! Here in the border area of E-France/SW-Germany, there is intensive cooperation between sheep farmers, nature conservation and hunters: https://www.biosphaerengebiet-alb.de/fileadmin/projekte/Kolkraben_Schafhaltung/BIO_21001_Kolkraben_barrierefrei_210908.pdf
Unfortunately, it seems to be a human-made problem, not a "bad character" of the birds. Flocks grow too fast because of warmer winters. And the problem seems to come only from the flocks of young males, never from couples.
@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.
