I am not sure what an appendage is but I think in this context, a penguins appendage would be its chick - its little chick that it rears.
Chick or a fledgling
AnswerA baby Penguin is called a Chick.
Baby penguins are called chicks or nestlings, but chick is the common and widely used term. They organize themselves in small groups called creches.
A baby penguin is called a "chick." A group of baby penguins is called a "Creche."
They keep the egg cratled in the father's feet
there chick can leave
So that the chick will live.
generally Update: No penguins are not asexual. It requires a male and female to produce a chick regardless of the species.
The chick makes a sound that the parents can recognize
lack of food
Penguins stop protecting their young chick when it is 8 months old because that is when it is big enough to take care of it's self and cope around the place alone.
