Re: What's the problem?
You've never been on a field trip to either South Wales or Northern Scotland then?
When the sheep weren't watching carefully for the perfect moment to punt you over or into hill/cliff/MOD facility electric fence, they were trying to grab your food (and I use the term under advisement) by main force.
Which in itself is odd if you think about it since a sheep's overriding ambition in life is being found dead, upside down with its legs in the air, in a clarty* hole.
*northern dialect word for slightly muddy bit*. Everyone else considers it to mean "that half mud/half slurry bit that just swallowed a 5ft6 teenage girl up to her shoulders". It didn't take too long to get her out, after we managed to stop laughing hysterically at an irate head poking out of the ground.
*muddy translates as "a large goopy pit in the middle of the path just deep enough for you to disappear up to your waist"
In Australia this ecological niche is filled by the Kangaroos - an animal that can kick your intestines out through your ears in one go. Male 'roo don't like male humans especially during mating season - what they think of female humans hasn't been imparted to me..
