He has this very peculiar habit with his grain. I never soaked it. When we moved the new BO gave me a funny look. He likes it runny. He licks it out of the tub, slops it around in his mouth with his neck stretched out. Then he licks the stall walls or grill and leaves a coating. He likes to nibble the dry crusty stuff.
He used to snatch dog food occasionally. He likes to nibble snow. He doesn’t like carrot cake. No watemelon. He turned down Guiness Stout even after I told him it’s a good source of nutients. No bananas but banana flavored Rounders are fine.
Goldfish crackers. Little Debbie oatmeal cookies with the frosting inside. Dandelions. He likes all sorts of weeds with flat leaves.
Lesson horses at our last barn: one gelding loved iced tea and donuts. Had to share my french fries with a mare once. Another mare that stopped at the same corner of the outdoor one day when she heard the explosive sounds of someone unwrapping a pepperment.
I’ve seen a few who like Coke or Pepsi.
