Poor sheeps

I hate having to lock the sheeps in the barn; I prefer letting them wander in and out as they please, but with forecast temperatures dropping to -10°F and wind chills down to -30°F, I don't want to risk their health.  I gave them some kitchen vegetable scraps and a half-scoop of molasses, which I sprinkled over their kibble.  They've also got tons of alfalfa, a mineral block and plenty of water in a heated bucket.  I'll probably let them out Saturday when temps climb back above freezing and the wind dies down.
