when i find whole chicken on sale, i use them to make chicken stock. simmer the whole chicken in a pot of water w/ veggies and seasoning for a couple of hours or over night (you could also crock pot it), pull out the chicken. strain the liquid and let it cool so you can skim off the fat. while the stock is cooling, you can literally pull the chicken meat right off the bone in chunks and shreds (i'm guessing of your chicken weight, about half will be actual usable meat). i freeze the meat to use when i cook later. when the stock is cool you can skim the fat off the top, package it up and freeze it too (the stock that is, not the fat!
). makes great chicken noodle soup, and you've already got the chunks of chicken to go in it!
