"We're not horsing around: These are very rare horse twins. Just thirteen hours after giving birth, "Lacy," an 11-year-old quarter horse tends to her two healthy fillies, on the Hacienda del S-Par farm in Stilwell, Kan. "Chantilly's Lace" and "Queen Anne's Lace" weighed in at about 35 lbs. each, small when compared to the usual 75-80 lbs. of a single-foal birth."
