The St Fagans National History Museum website will live stream the births of more than 150 lambs after an infrared camera was installed in one of its lambing sheds.
Farmers at Llwyn Yr Eos farm are expecting a baby boom in March after 97 of their ewes came in from the fields over Christmas for pregnancy scans. They are expecing 167 lambs next month.
Lambcam Live, which will launch in time for St David’s Day, will allow 24-hour access to see the new arrivals close up.
The museum flock has three breeds of sheep: Hill Radnor, Llanwenog and Black Welsh Mountain.
Bernice Parker, events and marketing officer at St Fagans, said: “We’re very excited about the project. It’s going to be a very busy March.”
Visitors to the museum can also participate in a Meet the Shepherd activity on St David’s Day and every weekend throughout March.
