Lacey is shedding too!
Around here, shedding is usually done in late April/early May. But it really depends on how many daylight hours your horse is getting. So, if he/she is under lights, he/she will shed a lot faster than a pasture kept horse. I've found that using a shedding blade daily really helps and once she's about half-way shed out, I usually give her the first bath of the season which takes care of a lot of hair.
