Why are penguins thought to have starved their chicks?

It was believed that they deliberately starved their chicks in order to force them to leave the breeding colony. This was founded on observations that the chicks of King Penguins (Aptenodytes patagonica) weighed more than adult birds and lost this weight prior to fledging.
