Same, same!I have a pot on the stove right now.
When I pick it I will collect all the bones, giblets, and bits -- including the skin which, having been first roasted and then simmered, hasn't much fat left -- and mix it up with the soup veggie trimmings. They love it.
Some people would avoid leaving the bones lying around. I let the small ones become one with the bedding and only rake out the larger ones that don't break down readily.
Ok, I burn the large bones, and then compost the bone meal. Otherwise, same same. Birds do love it.
