They don't.
Echidnas are monotremes, or egg-laying mammals.
After mating, there is a gestation period for the egg of 23 days. During breeding season, the female develops a rudimentary pouch which is really just a flap of skin. When it comes time to lay her egg, she curls tightly into a ball and lays it directly in this pouch, where it is incubated for around 10 days. The young emerge blind and hairless, and stay in the pouch, suckling for two to three months.

Do mammals give live birth to young?
All mammals, with the exception of the monotremes, give birth to live young. Monotremes are egg-laying mammals, and comprise just three species: platypus, short-beaked echidna and long-beaked echidna.
Do all mammals give birth to their young ones alive?
All except the platypus and the echidna.
What mammals give birth to live young?
All mammals have live birth except the echidna and the platypus, both of which lay eggs.
Is a bat a monotreme?
No. Monotremes are mammals which lay eggs rather than give birth. The only monotremes are the echidna and the platypus. Bats give live birth, so they are not monotremes.
Are raccoon babies born vaginally?
Yes. All mammals except the platypus give birth vaginally.
Do dogs give live birth?

Does a spiny anteater give birth to live young?
No. The proper name of the spiny anteater is echidna, and it is not related to anteaters at all. A female echidna lays a single egg every breeding season.
Do mammals give birth to live babies?
Yes, most mammals give birth to live babies. Only the platypus, and echidna (spiny ant-eater) lay eggs. Even marsupials such as the kangaroo give birth to live, albeit underdeveloped babies.
Can mammals lay eggs?
Almost all species of mammals give live birth. There are just three species of mammals which lay eggs: the platypus, the short-beaked echidna and the long-beaked echidna.
Do mammals give birth to a baby mammal in an egg?
No.Mammals give live birth, like a human baby coming out of of birth canal.Reptiles lay eggs, like a lizard or Dinosaur.Correction:There are two egg-laying mammals. The platypus and the echidna are both egg-laying mammals, or monotremes.They are still classified as mammals because they feed their young on mothers' milk - a characteristic unique to mammals alone.There are just three known species of egg-laying mammals, or monotremes. They are the platypus and short-beaked echidna (Tachyglossus aculeatus) of Australia, and the long-beaked echidna (Zaglosssus bruijni) of Papua New Guinea. The echidna is sometimes called the spiny anteater, and there are several sub-species of the long-beaked echidna: the Western long-beaked echidna, Sir David's long-beaked echidna and the Eastern long-beaked echidna.
