Cannibalism is one of the reactions of hens to the crowding of cage living. Debeaking at 12 to 17 weeks of age has provided a practical control of cannibalism in the past. The results of this trial show that early precision debeaking not only controlled cannibalism but also increased egg production, as compared with later debeaking.
