The aim of this project was to undertake a comprehensive independent literature review on layer hen welfare, with a particular focus on Australia, to inform current welfare discussions and the investment in welfare research and development.

This review was conducted by Australian poultry experts from multiple institutions. The review focused on research contextualised to Australia, but also consider international science. The literature reviewed focussed on the most recent publications that reflected current practice. The review considered all theoretical standpoints (biological functioning, natural behaviours and affective states) and presents all science based on its merits.
