Study: The Relation between Home-Pen Behaviours and the Affective State of Domestic Chickens Start date and duration: June 2024; 6 months. We will work in batches, so you will be assisting in training at least one batch of animals. However, you are welcome to continue working with us for a longer period if desired. Task: Training for the assessment of emotional state, sample collections, and data analysis Description: The affective state will be assessed using a cognitive judgement bias test and related to the behaviours expressed in the home-pen (e.g. social behaviour, comfort behaviour etc.). The results of this study will be used in a larger project that seeks to validate telomere length as an indicator of cumulative life experience. Requirements: All necessary equipment will be provided. Having your own computer is an advantage. Half full? Half empty?
