Turkey vs Chicken broth
Turkey fat will emulsify into the water at a lower temperature than chicken fat, so one key to clear turkey broth is to be careful to NOT boil it. You want an occasional burble, no more. Also, the proteins in turkey muscle tend to release their bound up water more readily than chicken (that's why turkey often becomes dry more easily than chicken does) and will begin to disintegrate. So the more meat in your carcass, especially white, the more cloudy it will appear.
