I just stumbled on this thread but am so happy to see it. I want to can meat too. My grandmother used to can it and it was always so tender, plus it makes a quick and easy meal.
I took a fermenting class a couple of weeks ago and a lady there cans chicken, beef and venison. She said it's pretty easy but you MUST use a pressure canner. She gave me a website that is very helpful and has some recipes too.

We buy most of our meat in bulk from Zaycon Fresh so I plan on trying to can chicken breasts in Feb. when I get my next 40# box from them. I haven't used a pressure canner in years so I'm a bit apprehensive but I am looking forward to it.
