Don't carry a bucket into the pasture unless you mean to FEED. Luckily our cows are gentle, but when we first bought the place, our neighbor ran less-socialized cattle here. As we naively strolled around picking invasive thistle heads into our buckets we couldn't figure our why we were being followed by the increasingly agitated herd. It took a few times of ditching over the fence to figure out why they kept trying to stampede us. DUH, cows are trained to follow a feed bucket and here we were taunting them with our mixed messages!
