Summary

In Switzerland, France and The Netherlands 257 farmers keeping free ranging laying hens (organic and conventional) were interviewed with regard to genotype of the hens, management conditions and performance. In total, 21 different genotypes were present on the farms. The overall effect of system (organic vs. conventional) on egg production and mortality was significant, with higher mortality and lower egg production among organic hens. White hens tended to perform better and have a better feather cover than brown hens. Silver hens appeared to have a higher mortality and lower production per hen housed. In group discussions, farmers preferred a more robust, heavier hen with good intake capacity and good persistence. In organic systems, this hen type is more economic according to model calculations.
