Reply to comment by QAoA in TIL When a cow has opposite sex twins, the female twin is usually born intersex and infertile. This happens because the twins blood supplies are linked, which exposes the female to male sex hormones. by awawe
No, cows generally have one and many don't survive having twins. I don't remember the exact amount but less than 5% of births are twins, and usually they are undersized due to lack of space. The fact this girl managed to have full size twins unassisted with both babies and momma surviving is shocking.
