The network aims to better understand the different factors that affect stress responsivity and stress resilience in laying hens. We go from the assumption that in the end, the stress resilience is based in the brains of the animals, but that the factors that determine this stress resilience are a combination of genetics, early-life experiences, and current (adult) environment. The network therefore aims to better understand how the stress response is regulated in the avian brain, but it also looks at all three factors that affect resilience. We don’t just want to understand what the effects of these different factors are, we also want to know what we can do to improve stress resilience in the future. Hopefully this will lead to new recommendations to the egg industry to improve laying hen welfare, by providing them with the resources to be more resilient to stress-full experiences.
