In a recent announcement, Kroger Supermarket chain announced that they will be shifting to totally cage free eggs by 2025, after placement of billboards advocating cage - free sourcing in and around Cincinnati, near Kroger's headquarters.

Notably, just a few weeks ago, Trader Joe's also announced that it would shift to completely cage - free supply chain by 2025. Last year, only 15 percent of Kroger's eggs were cage free.

"As our customer base has been moving to cage-free at an increasing rate, Kroger's goal is to transition to a 100% cage-free egg supply chain by 2025," the company said in a statement, according to The Daily Meal. "The Kroger family of stores is committed to working with our suppliers during this transition in a way that ensures eggs are readily available, safely produced, and affordably priced for all of our customers."

Although the supermarket chain is not the first one to switch to cage - free eggs, yet it is one of the few national grocers who have taken part in the campaign.

Additionally, the fact that Kroger's announcement was made a day after the Humane League, an animal welfare group launched a campaign to convince Kroger to change its egg - sourcing methods suggests that more campaigns launched can increase awareness among people.

Onlookers suggest that the billboards placed on benches in Cincinnati, just a few blocks from Kroger's headquarters, called on the company to "please help" the chickens in its supply chains.

A day later, Kroger conceded to public pressure and promised to "continue to listen to our customers and engage in dialogue with stakeholders on important food policy issues."

"We applaud Kroger for listening to the concerns of its customers and committing to end its support of cruel cage egg farms," David Coman-Hidy, executive director of The Humane League, said in a press release. "This will have a huge impact on the future of animal welfare in the U.S."
