Tufty has horns, the cows have bulk and everyone wants to eat concentrates.  When I take the cow buckets out to the field, Tufty tries to biff the cows to eat their food.  So, as quick as I can, I run into the field with a small bucket of sheep pellets and Tufty and Wiggle follow me and let the cows eat their concentrates undisturbed.  But when the cows have finished they rush over to where the sheep are eating and try to steal their food.  Horns versus bulk and so far the Rams are winning.
