My filly is being weaned (no longer nursing in the field, but still in the same pasture as her dam) and has demanded she eat in another bucket than her dam. How much should I feed the little one? In whatever unit of measure makes you happy! She's about 4 or 4 1/2 months old, 12.2hh, and has been on a high end mare and foal feed so far. Also, is there a feed you would recommend for her?
