Bone broth is always pretty gross.
Yes, it just has a ton of fat in it. Stick it in the fridge, pull the fat off and use it for frying things in. You can keep the broth going even if the bones are already crumbling - keep it going until the broth fades in colour. With my beef broth, often it's quite yellow at the beginning, then it gets a rich brown colour, then fades to pale brown after 6 days or so. Chicken is going to be different, though. Probably won't be able to do a 2-week broth from chicken bones.
When you decide you're done with broth, smash those bones up (probably even a cheap blender would do the trick if you added a bit of broth) and make some fudgesicles!!!
