Ferrets, like all mammals, are born live and do not develop within a protective sac like eggs do.
Here's why:
* Placental Mammals: Ferrets are placental mammals, meaning they develop inside the mother's uterus and receive nutrients and oxygen through a placenta.
* Umbilical Cord: Ferrets are connected to the placenta by an umbilical cord, which delivers nourishment and removes waste.
* Birth Process: Ferrets are born through the mother's vagina, just like other mammals.
