Simple Summary
The vocalisations that an animal produces could provide a window into its emotional state. More knowledge on how emotional states are expressed in the vocalisations of birds could even be used to improve the welfare of farmed poultry. The present study introduced a novel device designed to trigger different emotional states in hens u...

The hypothalamic–pituitary–adrenal (HPA) axis responsivity is influenced by early life experience and also modified by the environment an individual experiences as an adult. Because laying hens are transferred from rearing to laying farms at 16–18 weeks of age, they are well suited to study the interaction effect between early (rearing) and adult (...

Simple Summary: Recent studies have delved into the adverse phenomenon of smothering in cage-free laying hen-rearing systems, challenging the traditional notion of this behavior as “natural” or the result of hysteria among birds in the flock. This work identifies smothering as a detrimental, abnormal behavior with significant economi...
Modern poultry production entails a number of important animal welfare issues. However, welfare is often considered to be better in organic than in non-organic production, largely due to the focus on naturalness within the former which has been embedded within the EU regulations on organic production. The aim of this paper was to review the relevan...

... NMP: no addition of multifunctional platforms.previous studies have shown that enrichment can impact vocalizations:Golfidis et al. (2024) linked vocal changes to emotional stimuli via interactive feeders, andMeyer et al. (2024) reported reduced vocalizations under laser enrichment. Additionally, our data were not collected during acute stress events like fear tests or isolation, which typically elicit stronger vocal responses ...
