Other: Abrupt changes to the layers’ routine, loud noises, the introduction of new birds to the flock (mixing ages), pest challenges (especially red mites or vermin), and not removing injured or dead layers in a timely fashion can all contribute to increased feather pecking. • Increased feed intake: Feather loss causes hens to become colder, especially in severe cases where bald patches have appeared due to feather pecking. To maintain body heat, their feed intake needs to increase to maintain nutrients and energy lost as their bodies work harder to keep them warm. Feed density may need to be adjusted to prevent overconsumption of protein and other nutrients, as well as the mineral imbalances that can follow. • Welfare is negatively affected by the pain and injuries that feather pecking can cause. • Cannibalism affects the chicken’s value due to poor feathering and damaged flesh, and consequently decreased production and higher mortalities. • Economics: All the factors above ultimately have a large impact on the financial bottom line of the farming operation. Higher intakes, more mortalities and lower production all negatively impact the farm’s profitability. Prevention methods entail minimising stress factors on the farm by ensuring the correct stocking density, lighting and environmental temperature, isolating injured hens, and removing mortalities as soon as possible. Beak-trimming the hens as day-old chicks, matching housing conditions in rearing, and laying sheds as far as possible help prevent pecking injuries and stress. Layers should have ad lib access to a well-balanced ration from a reputable feed company. Consequences and prevention Conclusion Stress factors are the major cause of feather pecking, which can spread through a flock and lead to cannibalism, production loss, mortalities, and large profit losses. Excellent management is therefore key in preventing feather pecking and all the consequences thereof. www.deheus.co.za | 031 785 1575 | infosa@deheus.com Should you requiremore information relating to feather pecking in layer chickens, please contact your nearest De Heus technical specialist – https:// www.deheus.co.za/meet-our-team/. www.agribonus.co.za Spring/Summer 2025 BONUS 55
