Behind my chicken coop and next to our storm shelter is a large overgrown area my DH calls the milking lot. It's the area his mama used to bring her milk cows to milk em. There are THREE large openings into this lot, not including the opening in the fence next to my chicken coop. The other day our neighbor brought 150 young heifers up here to the farm and turned them loose in the meadow. Somehow 12 of these heifers got into the milking lot and couldn't figure out how to get back out of it. Since the night before last they have stood virtually in one spot. There's no water source up there and very little to graze on. If they had gone 200 ft. in any direction they would be back in the meadow with the rest of the herd, but nooooo they just stood there watching the other cows graze. The neighbor checks on the herd daily, but unless you were to stand in front of my chicken coop you couldn't see these cows "trapped" behind it. I finally took pity on the stupid beasts and called the neighbor to come rescue them. Proof positive that chickens are smarter than cows.
