Tbh the only time ive known sheep to knock anyone is when they are carrying a bucket of meal trying to feed the fuckers, the mother in law got knocked over by sheep who then walked over her to get to the feed, only time ive ever seen her lose her temper she started chasing them with the shovel in her hand yelling "walk on me will ye, I'll teach ya ta walk on me" was very funny as shes a tiny little old woman and such a nice person normally
