The family-dining chain said it aims to complete that transition within the next decade.
“For more than 60 years, we have listened to our guests to understand what they care about the most, without sacrificing on quality, taste or value," Denny’s CEO John Miller said in a statement. "The humane treatment of animals remains an important part of our brand's sourcing strategy, and our commitment to this transition underscores our confidence in the ethical evolution of supplier capabilities."
Denny’s announced the switch in a video showcasing a group of chickens debating what to do with their newfound freedom.
The chain said it serves more than 400 million eggs annually.
