I don't know how it could've happened. Had to have been sometime last night though, and I really don't know what she could've done to cause a chip like that.
Her farrier visit is scheduled for the 27th of this month, should I reschedule for as soon as possible? Does she need shoes to help it heal over? How serious is it? I don't really have any idea.
It doesn't seem to bother her at all, but I'm sure it can't be good..
