Answer:

The size and weight of a penguin chick differ according to the species; however, in the particular case of the Emperor penguin, one of the best-known penguins, the newborns weigh around 315 grams which compared with the adult weight up to 22- 37 Kg is a tiny fraction.

In contrast, the smallest penguin known as the Fairy Penguin weighs 35-47 grams.

Medium-size penguins like the Magellanic Penguin have an average weight of 57 grams when born.
