Most mammals do not lay eggs at all. Only the monotremes, or egg-laying mammals, reproduce by external eggs. Monotremes include just the platypus, the long-beaked echidna and the short-beaked echidna. These mammals lay eggs just once a year, each breeding season. Platypuses lay 1-3 eggs, while echidnas lay a single egg, just once each year.
