Chocolate milk stout blueberry recipie?

Has anyone ever added blueberries to there chocolate milk stout beer? I have had half choc stout and half blueberry beer mixed together in a glass and it was good but not sure if you can brew with the blueberries? any advice will be appreciated. thanks

I have two stouts recipes that I use blue berries in that I brew twice a year. The other one is blue and black Belgian stout For my half Irish family and half German. Every one love them on saint Patrick’s day. I use the cans used for wine and rack my beer on top of the fruit in secondary for around two weeks
