A buffet of litters – Broiler chickens behave differently according to litter type and freshness

Poultry are usually provided with a single litter type that may not satisfy all litter-directed behavioural functions and may lose functional value over time due to soiling and degradation. We investigated this hypothesis in two commercial broiler flocks reared to...

Better welfare for broiler chickens given more types of environmental enrichments and more space to enjoy them

Providing an increased variety of environmental enrichment options, with sufficient space to use them, could increase the behavioural expression of positive affective states in production animals. The goal of this study was to investigate associations between the number of different...

Animal agency, animal awareness and animal welfare

In nature, animals need to actively engage with the environment in order to prosper in survival and reproduction. Hence, agency is a central adaptive characteristic of animal life. In this paper, I propose that from the adaptive/functional point of view,...

Poultry welfare: Science or subjectivity? British Poultry Science 43(5), 643–652

1. Most people in the developed world agree on what “animal welfare” is, although it is impossible to give it a precise scientific definition. 2. The argument is made that animal welfare is all to do with the feelings of...

Farm animal enrichments improve the welfare of layer chicks and pullets: A comprehensive review

Currently, cage housing is regarded as a global mainstream production system for laying hens. However, limited living space and confinement of birds in cages cause welfare and health problems, such as feather pecking, osteoporosis, obesity, and premature aging. Many studies...

Environmental change or choice during early rearing improves behavioural adaptability in laying hen chicks

Laying hens are typically moved to a novel environment after rearing, requiring adaptability to cope with change. We hypothesized that the standard rearing of laying hen chicks, in non-changing environments with limited choices (a single variant of each resource), impairs...

Effects of stocking rate and environmental enrichment on the ontogeny of pecking behavior of laying hen pullets confined in aviary compartments during the first 4 weeks of life

The objective of this study was to describe the ontogeny of the severe feather pecking (SFP), gentle feather pecking (GFP), aggressive pecking (AP), and enrichment pecking (EP) of non-beak-trimmed Lohmann Brown (LB)-pullets during the first 4 weeks of life (observation...

Energy assessment from broiler chicks’ vocalization might help improve welfare and production

Vocalization seems to be a viable source of signal for assessing broiler welfare. However, it may require an understanding of the birds' signals, both quantitatively and qualitatively. The delivery of calls with a specific set of acoustic features must be...

Environmental complexity and reduced stocking density promote positive behavioral outcomes in broiler chickens

The objective was to evaluate the impacts of a complex environment and stocking density on Ross 708 broiler chicken behaviors. Eight pens contained either high complexity (HC) or low complexity (LC) environments, and high (HD) or low (LD) density. Through...
