We just started our first week-long spell of winter like weather where temperatures drop down into 20's F with highs in thirties and lower forties. The chickens get about 1/2 their nutrient needs by complete feeds early in morning and make up the difference by foraging. They could be covering about 8 acres, but they are so far doing less than half that. In the evening I feed sheep, goats and chickens. At this point chickens get only my scratch grains mix which made up of while greens. The chickens appear to be contracting their foraging further waiting for the grains, especially the shelled corn. The chill appears to have caused them to terminate foraging earlier when compared to when it was warmer, and the shelled corn is really being targeted. Dogs are also eating too.
