If you have a pressure canner you can also can your stock and save that valuable freezer space. Check your Ball Blue book or UGA site for times, but looks like 20 minutes for pints and 25 minutes for quarts at 10 pounds of pressure. If your'e really ambitious, make a day of it. Or two really, so you can let it cool and skim as much fat as possible. Saturday, whip up big pot of chicken soup, pull out chickens, cut off meat, etc, let cool, skim fat. While that's cooling, take bones, skin, etc make up batch of stock. Put that in fridge to cool, and skim fat and start canning the soup. When taht's all canned, go back and skim fat from stock, and can that. Long day, lots of work, but great homemade soup and stock for a while.
Edited to change pressure cooker to pressure canner. These are NOT the same thing (and I know that, just a brain fart, haven't had coffee yet
