Hopes are of course always high at the start of such an endeavour, and we all know how slow and twisted the paths from science to application can be. However, I do believe that we are (still) in a crucial time with regards to the changes in housing systems from the old battery cages to whatever the new standard will be. Cage-free egg production seems to be growing very rapidly, with the USA now starting to follow the example of Europe. However, there are still very many unanswered questions about the different cage-free systems. The parts of the network that I think are the most likely to make some real progress when it comes to laying hen welfare, are the projects aimed at understanding the best route from early-life experiences (incubation, hatching, rearing) to adult laying environment. By hopefully making some very concrete recommendations about how hens should be incubated, hatched and reared, so they can cope optimally with the new adult housing environments (e.g. using different levels in multi-tier barns, using the range in free-range systems), I hope that this network will contribute to the successful implementation of these new cage-free production systems, both in terms of animal welfare, and in terms of egg production.
