Part of the outside menagerie includes two miniature horses. Rocky and Desi are both gelded boys and they spend their days in a corral. I had purchased them initially with the intent of them being backyard grazers but then learned quickly that miniature horses can't handle too much grazing....or any in our instance. Desi came to us morbidly obese and had foundered in his last home. They didn't control what he ate and he literally ate himself sick on a giant round bale of brome. Rocky, whom I've had since he was six months old, used to be let out to munch on sweet grasses but would also get sick quickly. He had problems with colic in the first couple of years of life which our vet eventually narrowed down to food. Feed was switched and grazing was ceased and he's had no problems in years.
They are healthy little horses, but bored little horses. Luckily they have each other. Every evening they perform their little ritual of trying to murder each other. They've done this for years and I have watched it like a little TV show in the corral. I think they like to imagine they are tiny little dueling stallions. This goes on for about 20 minutes and then they are best friends again. Silly animals.
