Do you need to remove fat from broth?
It's necessary to skim the fat as you boil down stock to preserve the integrity of the flavors. You want the pure, meaty essence of the bird and the earthy goodness of the vegetables to shine through, not the fat.
Skimming the fat off stock or broth ensures clarity and lightness of flavour, two ideal qualities of a great soup, especially consommés.
Skim the fat off the top of the broth and discard it instead of eating it (this is the easiest route!). We can scoop off the oily layer while the broth is simmering, or remove it after refrigeration when the fat hardens and turns whitish or yellowish.
Some of my favorite cooking staples like pinto beans and broth are low-acid foods. This means that you can't safely use a water bath canner to preserve them. But, a pressure canner will do the job with no problem.
Our Test Kitchen finds the easiest way to remove the fat from the broth is to chill the broth first. Cover and refrigerate the soup or broth 6 to 8 hours or until the fat solidifies on the surface. Then use a spoon to easily lift off the hardened fat.
With boiling, any fat rendered by the meat or bones will be churned back into the broth instead of floating to the top where it can be skimmed off. Broth that has been boiled turns cloudy and has a greasy taste and feel.
Don't have a fat separator? Here's another, super simple way to separate fat from drippings or gravy. To separate fat from drippings or gravy, first put a large resealable plastic bag in a large bowl. Pour in the drippings or gravy; seal the bag and let it stand for several minutes, until the fat rises to the top.

Scoop the oil off the soup's surface with a soup skimmer, if you have one. If not, you can use a large spoon or a ladle instead. Drag the edge of the utensil just under the layer of oil to collect it, and then discard the contents of the skimmer, spoon or ladle.
If you leave the scum, it will break up into microscopic particles and disperse in your stock, making it cloudy. Straining later, even through layers of cheesecloth, won't remove it. Once it boils, the scum is there to stay. Cloudy broth is the worst case scenario, and, in my opinion, it really isn't that bad.
Why shouldnt you boil bone broth?
Just as when you're making stock for soups or stews, boiling will cause soluble proteins and rendered fat to emulsify into the cooking liquid. By simmering, you avoid emulsifying the fat and thus keep the stock clearer, and we found that the scum created simply settled to the bottom of the pot.
The longer the bones and meat cook, the more the proteases break the bonds connecting the proteins, and the more amino acids get detached (source). It just so happens that we taste many of these amino acids and protein fragments as bitter.

I like to skim my fat off to use in cooking or leave it in for added flavor. There is some debate on whether you need to skim the fat off your broth before canning. My general rule of thumb is if you're going to use the broth within six months of canning, you can leave the fat.

Simmer Your Bones Long Enough, But Not Too Long
Yet, if you cook your broth too long, it will develop overcooked, off-flavors that can become particularly unpleasant if you've added vegetables to the broth pot which tend to break down, tasting at once bitter and overly sweet.

First, if your bone broth hasn't set up and doesn't gel, it's still perfectly fine to eat. It may not be particularly rich in gelatin or protein, and it will certainly lack the body of a properly prepared broth, but there's no sense in throwing it away.
