CANTON, Mass. (AP) Dunkin' Donuts is looking to transition to all cage-free eggs worldwide.

Dunkin' Donuts said Monday that 10 percent of eggs sourced for breakfast sandwiches in the U.S. will be cage-free by 2016's end. The company also said it will assess its international supply chain to figure out how feasible that will be.

In 2013 Dunkin' Donuts reached its goal to make 5 percent of its eggs cage-free by that year.

Dunkin' Donuts also said that by 2022 it will only source in the U.S. pork that does not use gestation crates. A gestation crate is a metal pen that houses a female pig. The cages are small and don't allow pregnant pigs to turn around. Animal rights advocates consider gestation crates to be cruel.

Among those that have already taken steps to use more cage-free eggs and gestation-crate free pork include Burger King and Wendy's.

Dunkin' Donuts and Baskin-Robbins are part of Dunkin' Brands Group Inc., which is based in Canton, Massachusetts.

Shares of Dunkin' Brands rose 19 cents to $47.69 in afternoon trading.
