That is strange. Wonder if that could happen.
Now there was a cow in England that gave birth to triplets that were two different breeds. Twin belgian blues and a charlois calf. The cow was inseminated with two different bulls.

This occurs when more than one egg is present and is fertilized by more than one sperm- easy to have more than one daddy.
Okotoks, the term is superfetation I believe.
Thanks,never would have remembered that, so now I googled it and here is the info according to Wikipedia!
From Wikipedia, the free encyclopedia
Superfetation (also spelt superfoetation - see fetus) is the simultaneous occurrence of more than one stage of developing embryo in the same animal. In mammals it manifests as the formation of a fetus from a different menstrual cycle while another embryo is already present in the uterus. When there are two separate instances of fertilisation during the same cycle, it is known as superfecundation.
Superfetation is claimed to be common in some species of animals, but is extremely rare in humans. In mammals it can occur only where there are two uteri, or where the menstrual cycle continues through pregnancy. The risk with superfetation is that the second baby is often born prematurely, which can increase its odds of experiencing lung development problems
