Animal Board Invited Review: Intrinsic hedonic value, complexity, and possibility for action as essential characteristics of a welfare-friendly environment for animals

I. Veissier, C. Terlouw, R. Botreau, V. Deiss, S. Cowie

Published in 2026

Study examining how the hedonic value of the environment determines animal welfare. Welfare depends on a balance between positive emotions, environmental complexity and opportunities for behavioral expression: these factors must be optimized (rather than maximized), since an excess or a deficiency of any one of them can be harmful to welfare, with the optimal level varying by individual.

Fowl play: Do age and aviary design affect play in cage-free laying hens?

Xiaowen Ma, Vrinda Ambike, Valentina Bongiorno, Jacquelyn A. Jacobs, Janice C. Swanson, Tina M. Widowski, Janice M. Siegford

Published in 2026

Study showing that the play behavior of laying hens decreases significantly with age, and is influenced by aviary design and space allocation per bird. Certain activities, such as more frequent running or wing flapping, were influenced by aviary design and space per bird. The study concludes that housing configuration influences welfare and may interact with the hens' developmental stage.
