That poor baby is going to be one messed up horse if the owner is willing to leave all the basic beginning training work in the hands of kids, especially at such an impressionable age. And I'm just envisioning "friendly" herd being more of a knock you down trying to get the treats out of your pocket herd. If you don't have time for your horse, why are you even breeding?
I see so many ads for stallions on craigslist, where the photos are far away, horse is in a field, covered in mud, no nice conformation shots, not a whole lot if any showing, just "hey got a stallion, he's cute, kinda sweet, you should breed". If you are gonna advertise a stallion, pedigree, conformation pictures, professional pictures, show records ect., not just a half crap photo snapped while doing chores around the barn.
