    Does Any Mammal Lay Eggs?

    Today’s paleontologists tend to agree that different dinosaur species laid different amounts of eggs. While some species produced around 1 to 5 in a single sitting, others produced around 15 to 20. Paleontologists have even discovered that laid around 35 eggs at a time. Does Any Mammal Lay Eggs? large clutches of offspring constituted a common practice among the dinosaurs, and an advantageous one at that. Because predatory dinosaurs had a habit of devouring almost any eggs that they could find, laying a lot of eggs all at once became one of the best ways for female dinosaurs to ensure that at least one hatched successfully.

    “The size of the egg-laying market in the world is estimated at about 7 billion laying hens, and for each hen, a male chick is culled. The production of table eggs in the world is estimated at over two trillion eggs per year — over 80 million tons,” Cinnamon told The Times of Israel.Male chicks born to egg-laying hens cost more to care for than they would ever sell for as meat, unable to compete with meat chickens, or “broilers,” which are born to a different kind of hen. Broilers are typically larger breeds with more muscle content, chosen because they grow very large, very quickly.

    Re: Does Any Mammal Lay Eggs?

    Yes, some mammals lay eggs. These are known as monotremes, a group of primitive mammals that lay eggs instead of giving birth to live young like most other mammals. The monotremes consist of only five extant species, all found in Australia and New Guinea. The five species of monotremes are the platypus and four species of echidnas, also known as spiny anteaters. These animals have a unique reproductive system involving eggs, similar to reptiles and birds. After hatching from the egg, the young are nursed with milk the mother produces, like other mammals.

    It's worth noting that while monotremes are classified as mammals, they have some features that are more similar to reptiles, such as laying eggs and having a cloaca, which is a single opening for excretory and reproductive functions. Check this link right here now.
