The Yorkshire Vet season 12 episode 12
Episode title: Episode 12
A sheep is rushed into the practice to see Peter, after seriously injuring herself on a piece of metal. Peter thinks he can deal with the wound, but the bigger problem is that the ewe is pregnant with twins, and the lambs' lives are in danger. Tilly the tortoise is the star of the Cannon Hall Farm reptile house. But she's not been herself lately, and Matt's worried she might need extremely rare and complicated surgery to remove three eggs that she hasn't been able to pass.
