Balls of half chewed hay left on the stall floor are called quids and is an indication that the horse is unable to close the opposing occlusal surfaces of the teeth against each other. The purpose of chewing is to create a swallowable bolus but with this ability lost, the horse would rather spit out this ball and try again with a fresh bite of hay. Usually grass is not a problem or is significantly less of a problem.
