Vic twin penguins' sibling rivalry

Siblings often nab food off each other and fairy penguin twins at Melbourne Zoo are no exception.

Keepers had to separate the two chicks, hatched within a day of each other, after their rivalry over dinner left one plump and the other significantly underweight.

The smaller penguin is now in a humidicrib being hand-fed pilchard fillets four times a day.

Its gutsier sibling will be moved to a feeding school on Wednesday, where it will adjust to being fed by keepers instead of its parents, in preparation for joining the adults.

The twins are among nine fairy penguin chicks born at the zoo this breeding season.
