Penguin point has three new Humboldt penguin chicks: Realmuto, Harper and Nola.
"We named our penguin chicks after some Phillies players this year," said Amy Iviens, who cares for the penguins.
She weighs the birds every day.
"So we are at two kilograms today, so we are almost at 4 1/2 pounds," she said.
The chicks were hatched at the zoo in April and May. It's not known yet if they are male or female.
"In just a few weeks they will be fully grown, same size as their parents and will be out joining the rest of the group," Iviens explained.
6-year-old Alex Lynch of West Deptford knows what to do with to do with his empty plastic bottles.
"Throw it in the recycling can so it doesn't go into the animal's water so it doesn't kill them," he said.
"So there is a lot of plastic just floating in the ocean and it becomes a danger for penguins. A lot of animals will swallow it and it's threatening to them. So if we can reduce all of that plastic in the ocean it will be fantastic, not only for penguins but for other marine wildlife," Iviens said.
