Five years ago I planted a shelter belt of mainly broadleaves on the western boundary of the croft and have kept the grass under control with a mix of Roundup and strimming but I don't like using herbicide and strimming is hard work. So I thought , "geese can subsist on grass and two of them eat as much as a sheep but they don't eat trees." I ended up with six Embdens from three sources so plenty of genetic variation.
I've a good fence with and electrified wire on top to deter the deer and the geese are big and noisy so perhaps this will keep the foxes away. I was wrong two geese were taken and the survivors were very upset and frightened but they found their own solution to the fox problem.
I really don't understand why so many people think foxes are cute and cuddly creatures, they are wanton killers. Fifty years ago when I was lambing in Glen Isla on my early daily round of the hill I found 12 dead lambs strewn about their heads missing, they'd been killed for fun, by a fox. The next night the estate gamekeeper sat up with a rifle waiting for the fox to come back for more fun.... end of fox!
