Case study shows chicken strains differ in aggressiveness
Poultry scientists at ARS Poultry Genetics Laboratory Athens Ga restudied pecking behavior in White Leghorn and Rhode Island Red hens. Pairs from four Leghorn and two Rhode Island Red strains were tested at 20 38 and 56 weeks to determine aggression levels and recognition of superiors. Most data show clear strain differences in aggressiveness and egg production, with smaller birds often more dominant in pecking.
