I grew up on a ranch, which is actually quite different than a farm, but I still had to try out Farm Frenzy. I've never heard of bears on a dairy farm, but I guess its a serious problem in this game's version of reality.
Fun game, I definitely recommend it if you're looking for a distraction. It gets challenging quickly. Check out the guide if you get stuck, and please feel free to contribute your own tips. The guide is still a work in progress.
