<human>:  What are the differences between regular eggs and free-range eggs?
<bot>: Regular eggs come from hens that are kept in cages with limited space and access to resources. They typically have a more concentrated nutritional content, since the hens are unable to forage for food items. Free-range eggs come from hens that have the ability to roam and forage for food on pasturelands during the day. They generally have a more varied nutritional content since the hens are able to eat a more diverse diet. Free-range eggs also tend to be more expensive than regular eggs because of the extra feed and labour that goes into providing the hens with a good quality of life.
