Useful info-graphic for understanding egg labels. Apparently, the “Hormone-Free” label is a marketing gimmick because egg-laying hens aren’t given hormone.
Induced molting (or forced molting) is the practice by the commercial egg industry of artificially provoking a complete flock of hens to molt simultaneously.This temporary starving of the hens is seen as inhumane and is the main point of objection by critics and opponents of the practice. The alternative most often employed is to slaughter the hens instead of molting them. -Wikipedia
