As part of the ChickenStress European Training Network, there are currently 14 (!!) PhD studentships focusing on stress adaptability in laying hens being advertised across Europe.
The projects are part of a Horizon 2020 Marie Curie ETN program (CHICKENSTRESS).
The PhD positions all revolve around understanding the causes of chronic stress in birds (laying hens), and range widely in their focus: Some positions are comparative neuroscience projects, ranging from electrophysiology to anatomy, development and neuroethology. Some positions are bioinformatics projects, investigating genomics and epigenetics of the avian stress response. And some positions are animal behaviour projects, focusing on effects of early life, genetics and current environment on cognition, stress reactivity and other behavioural indicators.
Depending on the country, no Master degree is required.
