The lambs are living in Rebecca Bradley's house, until they can move to a school farm.
Rebecca Bradley, from Radcliffe-on-Trent, in Nottinghamshire, is mum to two children at Cotgrave Candleby Lane School and helps to run a small farm at the school.
The lambs are currently living in her house for a few weeks until they are strong enough to move into their new home at the school's farm. Ms Bradley, who has a degree in animal science, said: "It's great for the children to interact with the animals, both as a learning and as a therapy tool.The NFU said rearing lambs indoors was not standard practice. "It can happen where lambs are too frail to be left in the barn," a spokesperson said.
"Taking them into the house would generally only be in emergency situations and for a short period of time to keep a really close watch. "Orphan lambs need to be exposed to all the normal surroundings and bacteria to help their development and make the transition back as easy as possible."
