I thawed out 3 squirrels I had previously killed to add to the 5 I took last week for "chowder". I placed all of the pieces in the pressure cooker for 30 minutes using beef stock for moisture. There must have been one old limb chicken in the mix, because even after 30 minutes....I had 4 quarter pieces of what you could compare to "Super-Ball" material... grin All the rest just fell off the bone.
