“Many of the cage-free egg purchase pledges have implementation dates around 2025, which was thought to be the minimum amount of time required for the industry to convert from more than 90 percent cage-housed hens to being predominantly cage free.

Couple this with many consumers’ reluctance to pay the premium for cage-free eggs, and we have the current confusion in the marketplace where surplus cage-free eggs are being sold to breakers at substantial losses for egg producers.”
