Night blind horses do better in herds so they can follow their buddiesNo clue, since he was supposedly on solitary confinement in a little paddock when he did it, while recovering from an injury involving poking his own eye out (big nasty ulcer/hole in the middle of it, almost lost the entire globe due to swelling and potential rupture, had to have surgery and a shunt implanted through his neck to deliver medications 'round the clock....awesome). Best guess is that, being a homozygous Appaloosa, he is night blind and ran head-first into a post. But I don't really know.
I think he is gorgeous. But im kinda partial to those fewspots
