In the fall and winter they are normally still facing the back of their stalls, resting and letting any weather from the east break over their butts. In the warmer months Stormy is usually drowsing in the morning sun while Callie keeps the watch. As I trudge up the hill toward the stable Callie begins pawing her gate, which sags beneath her muscle-powered impatience. Stormy, never a paragon of patience, paws her floor mats relentlessly, monotonously and sometimes irritatingly.
Both horses are anxious and very hungry after a night in their stalls. Stormy has to pee and Callie can only think about the grass that grows just a few feet outside her stall.
In the last year Callie has begun to assert herself more and more,with small but dynamic changes in her behavior, while not challenging Stormy's leadership role. There are more flattened ears when Stormy approaches, defensive postures at feeding time, and once in a while she refuses to groom Stormy. Occasionally she has taken Stormy's food with almost no protest from Stormy, who defers without so much as a flick of her ears. But don't be misled, Stormy is still the leader of the herd.
