Sarah's horse comes in on saturday...(dec 20th), my 2 horses are out side 24/7 with a run in barn, sarah's new mare is use to being in a stall at night and turned out in the day time, my question because of this she dosn't have the think winter coat I would like her to have....just wondering if I should be blanketing her at night's while turned out and take it off in the mornings untill her coat get's thicker?
