NEWS 16 FEED & ADDITIVE MAGAZINE August 2025 A new paper from Denmark-based Aarhus University sheds light on an often overlooked but serious problem in egg-production: Feather pecking among egg-laying hens, which is a behaviour where hens peck at each other’s feathers. It can range from mild, social behaviour to feather pulling that can cause wounds, stress, and, in the worst cases, cannibalism. Therefore, feather pecking is categorised into two types: Gentle feather pecking and severe feather pecking. Although organic and freerange systems provide hens with more freedom of movement and better opportunities for natural behaviours, the report shows that these systems also pose a risk for development of feather pecking. This is partly due to larger group sizes, more complex social interactions, and variable environmental conditions. The report emphasises that feather pecking is not only a welfare issue but also has economic consequences due to increased mortality, reduced egg production, and the need for additional management efforts. Severe feather pecking can lead to wounds, infections, and, in the worst-case, cannibalism. Hens with feather and skin damage are more vulnerable to disease and parasites. There is a clear link between feather pecking and higher mortality rates. Hens need intact plumage to regulate their body temperature, and replacing lost feathers demands energy. When feathers are removed, the skin is exposed, which can attract further pecking and lead to bleeding. This can escalate into cannibalistic behaviour. Feather pecking can also spread within the flock, as hens learn the behaviour by observing others – especially during the rearing period. Feather pecking is not only physically harmful – it can also be psychologically distressing. Hens that are pecked likely experience pain and fear, even if they do not show obvious signs. Many hens respond with passivity and immobility, which may indicate a form of “learned helplessness” – a state where the animal stops trying to avoid repeated negative experiences.

This comprehensive and stringent assessment procedure ensures a high level of protection of human and animal health, and of the environment. The commission's decision only allows this genetically modified soybean to be imported for use in food and animal feed, but not to be cultivated in the EU. The authorisation is valid for 10 years, and any product produced from this genetically modified soybean will be subject to the EU's strict labelling and traceability rules. The commission had a legal obligation to decide on this authorisation after Member States did not reach a qualified majority either in favour or against the authorisation.
