What contributes to the Leghorn being an economical choice regarding feed consumption?

They possess one of the best feed-to-egg conversion ratios

The economic advantage of keeping Leghorns, particularly for homesteaders looking to manage expenses, is largely tied to their efficiency in metabolism and production. They are recognized for having one of the most superior feed-to-egg conversion ratios available in common breeds. This means that relative to the total amount of commercial feed they consume, they generate a significantly higher number of eggs compared to many other chicken breeds. While they are excellent foragers and will supplement their intake with bugs and weeds if allowed access to safe areas, this foraging is supplemental, not a replacement for balanced feed. It is the efficiency of converting feed input directly into high-volume egg output that makes them economical concerning feed bills.
