I been doing this for years and sure many of you are also.  I never throw chicken bones away from a cook.  I freeze and when need stock throw them in the pressure cooker with onion and celery.  Most come from Sam's rotisserie. I just cover bones with water and add black pepper.  30 minutes under pressure. This makes the best stock!  Somehow I never have beef bones
 and I love Pho.
