this depends on the species of penguin. A penguin only ever lays one egg at a time, but some species lay two eggs several days apart.
The Emperor Penguin and the King Penguin lay just one egg. All other species lay two eggs, although in several species, the first egg often does not hatch or is not incubated. This is the case for the Erect-Crested Penguin, the Macaroni Penguin, the Royal Penguin, the Snares Penguin and the Rockhopper Penguin. Galapagos Penguins may lay either 1 or 2 eggs.
just one egg
Penguins do not have 'litters', they lay eggs and usually lay one egg a year.
Usually two, though the larger species lay one.
a little penguin lays up to 567 eggs a week
The number of offspring per year for penguins varies by species. Most penguins typically produce one to two eggs per breeding season, with the majority of species laying a single egg. For example, Emperor penguins usually lay one egg, while species like the Gentoo penguin may lay two. Breeding seasons can vary, but generally, penguins raise one brood per year.
because it is easy for them to look after.
Usually, penguins lay one egg per breeding season.
This depends on the penguin species - for instance: Gentoo Penguins, Adelie Penguins and Rockhopper Penguins lay two eggs while King Penguins and Emperor Penguins lay just one egg.
Birds do not have live young, they lay eggs. It is possible to get a double yoked egg, but I don't know whether they are viable or not.
no, it only lays 1 like all other penguins
The Emperor Penguin lays a single egg each breeding season, which takes place in winter The male incubates the egg while the female goes out to feed in the ocean, and she generally does not return until spring. Incubation takes around 65 days, and during this time, the male survives on his own reserves of fat.
It is tricky for penguins to keep their eggs warm in the cold climate of Antarctica, and they have to hold the egg on top of their feet rather than allowing it to touch the ice. This can only be managed with one egg at a time.
