Not a good idea to let her foal twins. It is extremely rare that it turns out ok. Most of the time neither twin survives and you could even lose your mare. Think about those foals long legs getting tangled up inside the mare - how would she foal successfully? JMHO

It is highly unlikely that they are actually identical twins. Horses almost never do that. Identical would mean that a fertilized eqq has split, creating two embryo's. Most equine twinning occurs as a result of multiple folicles, thus multiple eggs, thus multiple fertilization. Alot of the time the mare will slip one of the embryo's naturally, but if not, you will have to have the vet pinch one of the embryo's so that it will die and the other will hopefully live. Ultrasound and a good vet is nessicary in cases of twins.
I did two embryo transfers this year and on both flushes we recovered twins embryo's. They were implanted into seperate mares and the first set has made it 42 days and everything is great. The second set hasn't had it's 16 day check yet (keeping my fingers crossed).
Good luck with your mare.

The chances of there being identical twins is just about nil. I "never say never", but I will be willing to stake a considerable amount of something on the fact that you do not have identical twins... :-)

Read the article about twinning on this web site (follow that link). It should provide you with all the information you need.

Bottom line? Do not attempt or expect this mare to go to term with twins! Fewer than 1% of twin pregnancies result in the birth of a live foal - most are lost either early or with a late-term abortion, which can even risk the mare's life.

Checking the DNA of the resulting foals would be the only way to confirm identical twins. Equine embryos do not undergo the "hatching out" process that other mammalian pregnancies do, and which results in the creation of (by splitting) identical twins in the event of the embryo being pinched down during the hatching process.

The oocyte ("egg") does not split. And this early in the pregnancy, there is no "sack".
