The Instant Pot (just going to call it IP from now on) is fantastic for making bone broth. DH gets perturbed at the "bags of junk" in the freezer, but they are free bone broth ingredients!
Save the bones from anything you cook that has bones. Chicken and turkey carcasses, ham bones, steak, pork, whatever. I haven't used fish, but I've read they can be included.
Save the ends from onions, garlic, celery, carrots. Check out this list of other stuff too.

This site taught me just about everything I know about making bone broth, and explains it way better than I can.

When the broth is done, I dump it into a big colander over my big stock pot. It will be very hot, so be careful! I pick out the bones with tongs. If the tongs smash them, I put them in a bowl. If the bones don't break, they go back into a bag, into the freezer, and get used in the next batch of broth. Yup, use them again.
I mush up the mushy bones and the mushy vegetables, and give it to the chickens. Not all at once, but about a cup at a time with their afternoon mash snack.
I put the broth into pint-and-a-half canning/freezing jars and let cool a bit on the counter. Then it goes into the fridge. Anything I don't use in a few days gets stored in the freezer. Leave the fat layer on the top, as it helps keep it fresh. Pick it off if you don't want the extra fat in whatever you use the broth for.
