If you are cutting the chicken up into pieces, ie drumsticks, wings, breast etc.
what I do is remove the thighs, drumsticks, wings, neck.
make the circle cut around the butt hole.
split the soft area under the tail from side to side.
then take a scissors, or a sharp knife and cut the chicken from back to front right along the back bone.
break the chicken open like a car hood.
all of the innards are right there and easy to get a hold of.
loosen up the crop and pull it out backwards with the wind pipe.
the lungs are tucked in the ribs.
take them out.
\ along the back bone on both sides toward the rear are two dark colored items.
those are the kidneys. they are held in with
a few tight cords. just run a knive through the cords and push the kidneys out with your finger of choice.
