My horses will do just about anything for breeders cubes, we had longhorns cows for awhile and would buy those breeders cubes for them to eat in the evening. One day fed one to one of my horses and they love them. Its also alot cheaper to buy a bag of those than the fancier horse treats. 2 of my horses wont touch pepperments etc. Now my walker will eat anything, we have had to chase him out of the cat food, chicken feed (got into the neighbors coop one day), and he's even shared a sausage, egg, and cheese biscuit with my daughter, so nothing is off limts according to him, he'll try anything. And he loves watermelon. He makes quite a mess with those when I gave him some in the past, the others not interested.
