Abstract

Coprophagy scores were higher when chicken scratch or sweet feed [cracked corn, grain, rolled corn/barley] were available than when popcorn was available. Levels of coprophagy may be lowered by offering wadging materials [e.g., corn cobs, fruit pits, cardboard, fruit peels] with the forage.
