During the recent cold snap, I found that I could put the wet lamb inside and the mother could finish licking the lamb. I found that a 125 watt bulb was sufficient. When temperatures got below zero, one may have to use a 250 watt bulb. I found that a 250 watt bulb got almost too warm and caused the lambs to leave.
I pulled the barrels out when the temperatures rose or after a couple of days.Submitted by John Hall, a Suffolk sheep breeder from Chestertown, Maryland.
