On May 26 , 2010 , a Rockwall , Texas , Quarter Horse maria named Lil Mis Bit Of West ( aka Gypsy ) give nascency to healthy matching foals . The birth of live twins is rare in horses , because one counterpart unremarkably dies well before foaling .
This month , concisely after celebrating their four - calendar month birthday , the similitude are doing well .
“ They are in fantabulous health and are growing up tight , ” say Randell Book , who owns the horses with his married woman , Kathy .

Both greyish brown filly , the foals were call Docs Cheyenne West and Docs Cimarron West . Their forefather , a Quarter Horse stallion named Docs Peppy Benz , have by Kenneth and Janice Campbell of Sanger , Texas , was euthanized in short after the breeding 10 calendar month to begin with , due to an injury sustained during an accident . This was the second breeding between Lil Mis Bit Of West and Docs Peppy Benz . The first resulted in a individual foal . Having two foal has meant double the effort in elevate them , according to Randell . “You have to buy milk supplement and feed each one , ” he says , referring to the fact that mares with twin often ca n’t produce enough Milk River for both baby . “ You also need to give the female horse extra food and supplements to help her bring about milk and stay in good form . ”Just like human Gemini the Twins , the twin fillies are similar in some ways and very different in others , Randell observes . “They are alike and unlike at the same fourth dimension , ” he say . “ They want to eat together but render to push each other away . If you work with one , the other gets one jealous . If one gets hurt the other one halt by her side as protection . ”Randell said the filly play together a mint , and when they need to be alone , they persist where they can still see each other . “If one filly draw out of sight , the other filly starts calling and take care for her , ” he pronounce . alive twin foal are uncommon because mares abort one or both of the similitude 70 percent of the time . Permanent damage to the mare ’s procreative nerve tract may occur in some shell . Twins can be detect early in a pregnancy with the help of sonography , and mare owners can elect to have one or both embryo murder to avoid possible complications . In Gypsy ’s fount , no ultrasound was performed , so the Books were unaware of the duplicate maternity until the twenty-four hour period of the foaling .
“ When I realized Gypsy was going to have the 2d foal , I was scared and excited , Randell says . “ Gypsy was very tired , so I had to [ help ] hand over the second Twin Falls . ”
The duplicate filly are part of the Books ’ belittled Foundation Quarter Horse breeding program . “We have a diminished place right now but want to get liberal and multiply the all - around horse , ” Randell say .

The fillies carry the bloodlines of the broadcast ’s well - known buck , including Mercedes Benz , Leo , Poco Lena , Lighting Bar , Three Bars , Midway , Old DJ , Way Out West , King and others .
