I have seen badgers take pheasants on my brother in laws farm. I would not shoot them for that personally but I would love a rock solid reason to shoot them on sight, bloody things. Never seen one attack a lamb but I would not be suprised to see it happen. Badgers are aggressive gits.
Back to foxes though. They are simply opportunists. They are not born to destroy lambs or chickens or whatever. They are omnivores and will dine on what is available to them. I don't live on cheesecakes but if you put a load on the table in front of me, I will eat them.
There is probably little thermal footage of fox attacks, as those who do see this about to unfold or in the middle of it, will almost certainly be stood there with a gun to deal with the issue. I have seen foxes attack all manner of things but I don't sit there recording it, I shoot the thing.
Apart from one place where I shoot which is a local golf course. I help them out with a rabbit problem but foxes are left as the owner feels they do no harm, despite me seeing them digging and crapping all over the course. Anyhow I can record them at my leisure on thermal as I am not there to shoot them. I see them doing some random things but mostly they just follow me round and steal the rabbits I shoot before I can get to them. They are so quick and switched on. The less effort they have put to put in for a meal, the better. I can understand that which is why I eat more convenience food than I should.
This one nicked a rabbit that was half the size of it. I was surprised at how quickly it legged it with such a large gobfull ha ha ha.
