Some snakes.
Animals which produce their young in this way are known as "ovoviviparous".
when an animal produces eggs that are hatched within the body,so that the young are born alive.

A mammal has hair and produces milk and the only mammal that is hatched is the plataypus.
There isn't just one type of animal, hun. Every single mammal. :)
hatched from eggs
Ovoviviparous - note that the third letter is an 'o', not an 'i' - means producing young by means of eggs that are hatched within the body of the parent - as in some snakes.This is different from* Oviparous - which means producing young by means of eggs that are hatched after they have been laid by the parentand * Viviparous - which means producing live young that have developed within the body of the parent
I believe that Pigeons and Flamingos produce a 'crop milk' that they feed to their young by regurgitation.
They area hatched from eggs which the female gives birth to.
The brown rat produces the most young in a year
It's animal whose young develop in the mother's womb (such as in the case of mammals) and are born live, and not in an egg that hasn't hatched yet.
Monkeys are mammals. The definition of a mammal is an animal which gives birth to live young and feeds them with milk. Monkeys are also our "cousins" genetically speaking - were you hatched from an egg? No, so neither is a monkey.
When first hatched, a baby platypus is completely hairless. The fur begins to grow within a week or so, but it is not visible for several weeks.
