Most mammals do not lay eggs at all, but give birth to live young.
The only mammals which lay eggs - the platypus and the echidna - are known as monotremes. The platypus lays its eggs on land, in a chamber at the end of a long burrow it digs in the riverbank or creek bank. The echidna actually develops a rudimentary pouch into which it lays a single egg during breeding season.
