Pardon my finch … have you seen my juicy garland?

We have a responsibility to promote a Culture of Care to ensure that all species have an appropriate positive environment. Enrichment provides holistic welfare opportunities for captive animals enabling them to demonstrate their natural behaviour. Commercially available enrichment is usually...

Dimensions of corvid consciousness

Corvids have long been a target of public fascination and of scientific attention, particularly in the study of animal minds. Using Birch et al.’s (2020) 5-dimensional framework for animal consciousness we ask what it is like to be a corvid...

Validation of enhanced floor pen housing for chickens

This study assesses the transition from isolator housing to an enhanced floor pen system for chickens, with the goal of improving Animal Welfare and promoting natural behaviours. Historically, chickens in our facility were housed in isolators, which limited the opportunities...

To what extent do chickens suffer when gassed with CO2?

On 9 th June 2025, in an apparent world first, undercover footage of chickens being gassed to death, in the UK in 2024, was publicly released (Carbstrong, 2025). The footage depicts a CO2 gas pit system within which crated chickens...

Fermentation bed farming improves behavioral expression and stress resistance in geese

Introduction Conventional livestock farming restricts the expression of natural behaviors and exacerbates animal stress responses. This study investigated the effects of fermentation bed farming, a novel welfare-oriented system, on the behavior and stress resistance of geese.Methods240 Northern White Geese (‌Anser...

Fecal glucocorticoid metabolites as stress biomarkers in common buzzards (Buteo buteo) across rehabilitation phases: Implications for raptor welfare

Taking wildlife into human care is a balancing act between benefits and harms, as handling and captivity can cause chronic stress that can lead to permanent physiological changes. Therefore, it is necessary to investigate stress levels during the rehabilitation of...

The influence of different light spectra on broiler chicken endocrine systems and productivity

In birds, light can penetrate the cranial bones and reach deep brain regions, where non-visual photoreceptors, especially in the hypothalamus, detect spectral and photoperiodic cues. Alongside retinal photoreception, deep-brain light sensing contributes to circadian entrainment and regulates melatonin secretion by...

Automated, stress-free, and precise measurement of songbird weight in neuroscience experiments

Monitoring the health and well-being of research animals is essential for both ethical and scientific purposes. In songbirds, body weight is one of the main indicators of their overall condition, yet traditional weighing methods can be intrusive and stress-inducing, which...

The effect of rearing environment on feather pecking in young and adult laying hens

Although the rearing period has an important influence on the development of feather pecking in laying hens, few studies have quantified the risk factors operating on commercial farms during this time and identified their long-term impact. Our aim was to...

Feather pecking in non-beak-trimmed and beak-trimmed laying hens on commercial farms with aviaries

Severe feather pecking (SFP) is a major animal welfare problem in layers. It results in pain and injuries in the affected animal. SFP is a behavioral disorder and should not be confused with aggressive pecking. The aim of our study...
