They have been in the barn since they were born, in a large baby pool with a red heat lamb. We've had temps near zero, but they seem to be plenty warm. I rarely see them directly under the lamp.
They are such an adorable bunch! All chunky, active and thriving. Belle is doing great as a first time mother. She had the barn to herself for the first couple of weeks, but now it's open and the sheep come and go.
