My weaned heifer calves, bred yearling heifers and bred cows all spend the winter in one sacrifice pasture together. They seem to do just fine as long as I provide enough hay feeder space for them. I do not have enough bunk space but it doesn't matter since they get almost no grain. The fenceline bunks in the corral are just for treat grain occasionally to keep them coming into the corral when i call.
