About the Project
Understanding the qualities of captive environments that cause abnormal behaviour has been a major topic in animal welfare. However, smothering - a type of abnormal behaviour in hens - has received little study to date. ‘Creeping’ smothering behaviour is where a high density of birds begins collectively milling and moving, and results in the death of hens by suffocation. Little is known about the causes of smothering and yet it accounts for 21% of flock mortality in laying hens and is UK egg producers’ top health and welfare concern. This project will use agent-based modelling of hen collective movements to identify the behavioural mechanisms causing smothering. Mechanistic data-driven agent-based models will be developed and parameterized with empirical data from video tracking of hens, and experiments performed on the models.
The objectives of the project are:
1. Analyze data from automated tracking of hens to understand mechanisms behind movements of individuals
2. Develop a mechanistic agent-based model that reproduces the collective behaviour
3. Implement data-informed differences between individuals to examine the effect of heterogeneity on the frequency of smothering
4. Experiment with the model to understand the conditions under which smothering is most and least likely to occur
