I don't like to raw pack. During cooking, it all cooks together into a big lump! (I can pieces, not whole breasts). I had about 25lbs of breast and quarters to can, so I pre-cooked in aluminum turkey roasters. (Too much for my largest pot, and I got to throw the messy pans away!) I boned the chix, put it into baggies and used the bones to make broth. then I diced the chicken and combined it with the broth from the bones and processed it for pints. Came out good.
