Starbucks has announced that all of its eggs will be cage-free by the year 2020.

The company’s plan is to have only cage-free eggs in its North American stores in five years, it told Reuters. Starbucks says it has been working on moving toward cage-free eggs since 2008.

McDonald’s recently made similar pledges, saying it is going to be making the switch to cage-free eggs over the next decade. Burger King has also made a cage-free commitment, set to be met by 2017.

The U.S. government defines “cage-free” as chickens having enough room to move around, though they may still be confined to cage. That change can lead to increasing costs for companies initially, Reuters says.

As Jacob Koffler writes for TIME, the transition to cage-free eggs has been a priority for both egg producers and activists for years, but efforts at a legislative solution have been stymied by opposition from pork and veal farmers who feared they too would face similar regulations.
