Hay cubes for Miniature Horses and goats! They work perfectly. They are small, break easily (for the most part) into bite sized treats and they're healthy. The only thing that worries me is the high calcium in Alfalfa, but it's only half and it's only for training treats and Chrome's two, so surely it won't affect his growth. Here's a picture showing the size . . .
And Chrome, Faran and Zep all LOVE them. :D That's the best part. Chrome liked the green beans (which I'll still probably use when I can grow some just to mix things up), but the others didn't and the split green peas were too small. These cubes however appear to be perfect. :) Chrome gets a little gummed up (like eating peanut butter), but it only takes him a minute to work it out of his teeth. It didn't seem to distract him from training at all.
Also here is a video I took yesterday just for fun. It's a short one of Chrome playing on his pedestal.
I'm so happy we've finally found something for treats that is affordable, easy to store in large amounts, healthy and easy to prepare and use. :) Yay!
