Although I can't think I would EVER have use for a canned chicken, I actually didn't think it looked that bad- for a boiled chicken.
Most of those juices around it were just that- the gelatinous stuff that leaks out of any chicken during roasting- it's delicious in gravy, and stock is like that if you make it yourself.
That said, it did look revolting being birthed from the can in that way. And I agree that it does look rather like confit de canard, including the texture.
