So you loose about 30% of the live weight after processing. That would mean your biggest "over 8 pounds" would have a live weight a little around 10 1/2 lbs. I suspect that's for roosters? But in any event.. that's just a little shy of what I had been processing mine at. I go more by how sorry I feel for them more than anything. They get so big they can't hardly move and that's when I say ok time to process, winner winner chicken dinner
i don't know the temp. I bring the canner to a boil, take it outside and put my little Coleman stove under it and dip them. dip them for a few secs, pull it out and see if the wing tip feathers come out easily. if not dio them again. don't hold them in too long or it will cook the skin.
