Cybercat, last year was my first time to pressure can chicken, and I canned it bone-in. This is fine with large meaty peises like, legs, thighs, and breasts. Pieces with smaller bones though, it's hard to get the bones out, because they crumble. Not a real big deal, because if you miss a bit, it just kind of mushes down anyway, but I decided to do it differently, because of this. Backs, necks, maybe wings and drumsticks, I'll save to cook in the crock pot. They get plenty tender, and the bones are solid enough to remove more easily. I may can some wings and drumsticks, too, bone-in, they're pretty easy to de-bone. Thighs and breasts are easy to fillet, so I'll can those. Then I'll have the best of both.
That's all for older birds. Young tender meat birds, I'd rather freeze, so I can make fried chicken, or roast whole.
Pressure canned chicken bones are ok to feed pets, they don't splinter. They're soft enough not to be a problem. Good source of calcium and other minerals.
