The hosses were in the west pasture, which is adjacent to the neighbor's pasture and his horses were turned out too. At dinner time, we just go to the gate, shake the feed buckets with grain in them, and whistle. The horses sometimes take their time, sometimes they run.
Today... ALL the horses came running, including the neighbor's horses

Then they stood at the fence and whinnied when they didn't get their dinner too

I felt so bad
