We found that putting the bale on it’s side worked better than on it’s end. Less chance of the bale plugging up and easier for the sheep to pull out. Also, better for shedding water and snow. If the hay is short enough, the sheep will eat into the side and the bale will simply tip over. If the hay is long, it’s just a matter of pulling down the hay from the top with a pitch fork.
Lambs also have access to formulated grain pellets during the lambing season up until they go on grass.
