Feed management for layers in enriched colonies

摘要

Enriched colonies are gaining ground in countries outside the EU, where they have been enforced by law, but how to best feed hens in this new housing system remains a matter of discovery.The recent transition in the European Union from battery cages to enriched colonies as a means of housing egg layers has created a number of questions regarding their nutrition. As with every change, observations and questions abound, but answers are away from being clear enough. Nevertheless, it is interesting to review the most common issues even at such preliminary stage, if only to increase awareness and cause further discussion.
