I haven't read all the posts, but I noticed some questions about cooking birds in the pressure cooker.  Here's what I've done.  Butcher and skin the bird, let rest in the fridge 48 hours.  I then rewash and bag the whole (small) bird and the freeze it until needed.  Again, these were small heritage birds.  I then pop the frozen bird in a the pressure cooker, and water up to 2/3 full or less (can be just to cover the bird), and add salt, celery, onion, and whatever else I want in there.  Then I bring it up to pressure, cook for about 12 minutes at full (no dial) pressure, then quick release.   The meat was perfect -- ready to fall off the bones and I had stock left over.  I then take the meat and make whatever I want with it.  I consider this the cheater's way because I don't like the mess of defrosting the bird in the fridge.  I don't save the gizzard or giblets, so that isn't included in how I cook.
