Meat or chicken you are referring to? If it is chicken, I believe all 🐔 from all poultry plants is slaughtered according to Islamic principles. I believe the same applies to all meat.
I would call the deli counter or the meat counter and ask. I'm sure they do have halal products available of it's not done in house.
I don't know about halal but they have a lot of meat...lots of meat.
