Warm Cows Are Happy Cows

My daughter is in 4H and has a calf we are raising in a shed behind the house. Recently, the bulb burned out on the heat lamp we leave on to keep the cow warm. Is there a simple circuit I could use to remotely monitor the temperature and alert me if it drops below a set point? I know there are remote temperature gauges but I need one with an alert or a way to hack one to add an alert. Any ideas welcome.
