Let's see what that smells like better.
After mouthing a goat kids ear the donkey curled her upper lip up like a Billy goat does after he gets his nose in the stream of a nanny goats pee. I always figured he is a cheaper version of those little sticks that women use to see if they are pregnant or not. I call it “pregnancy checking”. I have no idea why the donkey did it with the kid’s ear.
