"I knew we might be in for multiple births but definitely not four," he said.
"Plenty of ewes will have four lambs but for all four to survive birth is another thing," he said.
Mr Jones supplements feed for the four little lambs he has named Lamb Chops, Lamb Roast, Leg of Lamb and Lamb Rack.
"Three times a day I go in with a bottle and make sure none are hungry," he said.
"They will all survive now, especially with the plastic bags to help keep them warm."
He said his four children have each got their eyes on a lamb to go in the freezer for Christmas dinner.
