In this thesis project, you will study how factors such as shelter, stimulation, and early outdoor access can help prepare laying hen chicks for life as adult laying hens. Through behavioural observations and behavioural tests, we will investigate how chicks are affected by growing up in environments where they can move between a safe resting area and a stimulating activity zone. The goal is to promote positive animal welfare and resilience in the chicks.
Even though laying hen chicks are provided with a protected rearing environment today, they may still perceive their surroundings as unsafe. This can lead to fear and poor use of important resources, which may result in behavioral and health issues.
Our hypothesis is that chicks raised in environments with functional areas will spend more time engaging in activities that promote growth, learning, and well-being. These individuals are likely to be more resilient, have stronger immune systems, and be more inclined to explore new environments—including outdoor spaces when given the chance.
In addition to behavioral studies, there is an opportunity to explore immunological responses, monoamines, or examine the impact on neurogenesis and telomere length. This will provide deeper insight into how early life experiences affect the chicks' long-term health and well-being.
This thesis project offers you the opportunity to combine observations of the birds in their home environment with individual tests to evaluate the effects of early life experiences. Whether you are a bachelor’s or master’s student, this is a chance to contribute to the development of sustainable methods for rearing environments for laying hen chicks.
Data will be collected summer/autumn 2025.
