I have heard people talk about it that have tried it. It doesn't hold up to the pressure canning process very well.
I have posted my chicken soup process in other threads, but I will post it here as well

not bad for about $30 worth of materials!
Now the details....
even in my 31 qt all American pressure caner, I can only fit 20lbs of thighs at a time. I did 2 batches of 20 lbs each to prep but I took 1 package of carrots, 1 package of celery, 5 lbs of onions, 1 packet of fresh rosemary, 1 packet of fresh thyme, pepper corns. I put all of the herbs and seasonings in a cotton bag and tossed in. the celery and carrots get tosse3d in whole. Onions get halved. Garlic I cut entire heads in halve and tossed in. Add water until all is covered.
I pressure cook at 15lbs for 5 mins after pressure is reached then cool. dump whole mess through pasta maker pot into 5 galloln food safe bucket, repeat process for other 20lbs chicken.
Remove all of the "spent" vegetables and either eat them as a side dish, or feed them to the chickens or the dogs. Believe it or not after being stewed with all of that chicken the dogs will make short work of all of those veggies!
Remove chicken from bones and skin (reserve bones and skin). Chop second bag of carrots and celery, cut other 5 lbs of onions, break up 3 heads of garlic then cut cloves into large chunks. add handfuls of chicken to 14 quart jars, then add equal amounts of everything else, then fill with broth, and process.
fill jars with leftover meat, fill with water (there is enough residual fat to turn said water into broth during processing). process...
fill as many jars as you can with remainder of broth, process....
The chicken soup comes out SO rich and flavorful you can add about a quart of water to a quart of soup and it comes out about right in flavor. I also like to buy a big bag of the Amish style noodles that walmart sells, cook them according to the instructions until they are almost done then dump out most of the water reserving +/- one quart of water, then dump a quart of the chicken soup in and let it all heat back up. this makes a TON of hot homemade chicken soup. It takes the G/F and I a couple of days to finish it all!
I then put the skin and bones removed from chicken back in the pressure caner with about 2" of water in the bottom and pressure cook at 15lb for about 5 minutes after the caner has reached temperature. I remove the mess from the caner and use a potato masher to mash the now soft bones into a mash and feed to the dogs over their food for a few days.
Absolutely EVERYTHING gets used.
