That is when a large chunk of it separates and becomes another, smaller, iceberg.
An Iceberg.
Any iceberg (calved from glaciers) is typically several decades old, perhaps a century.

B-15 - The largest iceberg recorded, measuring around 11,000 square kilometers. A-68 - Another massive iceberg that split from the Larsen C Ice Shelf in 2017. C-19 - A large iceberg that broke off the Ross Ice Shelf in Antarctica. A-74 - A massive iceberg that calved from the Brunt Ice Shelf in 2021. C-16 - An iceberg that broke off the Pine Island Glacier Ice Shelf in Antarctica. D-16 - A large iceberg that calved from the Amery Ice Shelf in Antarctica.

I think you mean, "An iceberg has been calved." This means that, as a glacier moves into the waters of a sea or inlet, large chunks of ice, or icebergs, split off from the glacier and fall into the water. The glacier "calves" icebergs; the reference is to a cow giving birth to a calf.
The biggest iceberg ever recorded was Iceberg B-15, which calved from the Ross Ice Shelf in Antarctica in 2000. It was initially about 4,250 square miles in size, roughly the size of the state of Connecticut.
It has endured long months of pregnancy and given birth to a massive, mammalian aquatic animal. It has endured long months of pregnancy and given birth to a massive, mammalian aquatic animal.
Since this event pre-dated human history, there is no record of it. That said, the first iceberg calved off the Antarctic ice sheet in much the same way as icebergs calve off today.
Calfed is a homophone for calved.
Icebergs can vary enormously in size. The largest known iceberg, Iceberg B-15 which calved from the Ross Ice Shelf in March 2000 was 295,000 metres long and 37,000 metres wide. It had a surface area of 11,000,000,000 square metres.
A large detached piece of a glacier is called an iceberg. The process by which this happens is called calving.There isn't really a term for a detached piece of an iceberg. See related question.
