Improved Agricultural Animal Pathfinding

Seeing your agricultual animals (cows, pigs, chickens, sheep, etc.) shove their faces in the gate and the fence is very annoying. These animals should be given improved pathfinding. What I mean is whenever an enclosure is made around these animals they wander around the open space of that enclosure rather than looking like they're desperately hoping to escape. The only circumstance animals should shove their face in the gate is a lack of grass (so they can eat).
