RARE twin calves have been born in Purbeck.

Clover and Bob were born at the National Trust’s Greenlands Farm to proud mum Ellabella.

The day-old red Devon calves are being taken care of by Lisa Hawthornthwaite, who hit the headlines when she became Britain’s only cowgirl, looking after a herd of 30 cattle, which roam the Purbeck heathland.

The latest additions were named by Lisa’s daughter Charlotte, aged nine.

It is rare for red Devon cows to give birth to twins and Lisa had no inkling that anything unusual was going on until the second calf arrived.

She said: “We’ve never had a set of twins at Greenland Farm before so this is a new one on us.”

“We only thought she was having one calf and then within an hour she popped the other one out. We had no warning at all.”

The calves will spend their first week indoors while Lisa makes sure Ellabella is able to provide them with enough milk.

All being well, they will then move out into a field near the farm buildings until they are old enough to join the main herd.

Clover and Bob can look forward to a life roaming Studland and Godlingston Heath.
