"Conjoined twins occur in one out of every 50,000 births. Many such pregnancies are terminated before birth, or the infants are stillborn. Conjoined twins are always identical and of the same sex. They are more often female than male, by a ratio of 3:1. Conjoined twins are more likely to occur in Africa, India, or China than in the United States. Conjoined twins have appeared in triplet and quadruplet births, but no cases of conjoined triplets or quadruplets have ever been reported. Most parents of conjoined twins are younger than 35 years old." http://encyclopedias.families.com/conjoined-twins-272-275-gecd

No because when you have triplets 2 of the babys are from the same egg but the third is not. It is from a separt egg which means there is a separt sack around it.

Can conjoined triplets (or other higher multiples) exist? Dr. Rowena Spencer's 2003 book Conjoined Twins: Developmental Malformations and Clinical Implications discusses several cases of supposed conjoined triplets and quadruplets, most of which consist of one autosite with a number of parasites or acardiac twins (see above). However, a 2004 article in The American Journal of Obstetrics and Gynecology describes a case of parapagus dicephalus dibrachius dipus twins with triplet joined to the shared sternum, in the manner of xiphopagus twins. All three fetuses were well-formed and had approximately normal heads and extremities. This article provides conclusive proof that conjoined triplets, although extremely uncommon, can occur. http://www.phreeque.com/conjoined_twins.html

There has been only one confirmed case of conjoined triplets. Conjoined siblings occur only in monozygotic multiples. Triplets are most often what is commonly referred to as "a pair and a spare" meaning two are identical and one is fraternal. Two eggs are fertilized and one splits. Identical triplets are very rare, occurring in about 1/200,000 births. They are always the same sex. I am the grandmother of identical triplet girls born in 1998. They suffered from Twin to Twin Transfusion syndrome with one donor baby and two recipient babies. Their birth weights at 31/6 were between 1190gr-1759gr. At 10 years they are healthy, normal girls.

Yes. In 1896, in a small town in Northeastern Mississippi, Brother Jared Thomas owned a famed razorback hog named Honey, crowned the Sow Queen of the Delta. Brother Jared bred Honey to the local swine after being faced with foreclosure upon his family farm. Honey was a prize winning hog, keeping home and hogs fed during hard economic times, and Brother Jared prayed for "more of her". Jared was dismayed when Honey gave birth to a "deformed" litter of conjoined triplet piglets. Doomed to the slaughterhouse, the piglets had little chance for survival until the famed veterinarian, Dr. Albert Meister attempted the first surgical cleavage of newborn swine. Unfortunately, as he concluded the surgical procedure, Dr. Meister suffered a grand mal seizure, and flung the largest and most robust piglet onto a large gurney. The gurney rolled down the hallway onto a ramp, accelerating to frightening speeds towards the crematorium. The rest is history. Brother Jared gave up his life on the farm and found a new career as a restauteur. To this very day, at barbeque stands throughout Mississippi, one can enjoy Brother Jared's Babyback Ribs.

Not with a credible confirmed source. Except for pigs.
