Yup, I had a lamb this year which had it’s tongue and eyes taken by a crow. Horrible, particularly as you’re usually left with a lamb that is perfectly healthy but can’t suck or see. The lamb in question this year died within minutes of lambing, presumably of shock.
In a strange way I’d rather lose them to foxes – I usually lose them to a vixen who takes the whole lamb for her cubs.
I was out shearing in Colorado a few years ago, the couple I stayed with had a mountain lion climb their fences (8’+), then take a 30kg lamb back over the fence! They now have livestock guardian dogs (not to mention an arsenal of weapons to rival many small countries!). In many ways I think we, in the UK, are pretty lucky with predators (although out of control pets is another issue…).
