Nutrition Information of Homemade Chicken Stock

I'm sure this has been covered before.

I genuinely have no idea. Googling it tells me that it can be anywhere from 18 calories per cup to 260 calories per cup.

I made some home made chicken stock/broth today for some chicken pho tomorrow. I use 1 pound of chicken backs/necks. I added charred ginger, charred onion, cloves, coriander, fish sauce, one teaspoon of palm sugar, and two pieces of star anise. I'm refrigerating it overnight, and tomorrow I will pull off all the fat that has risen and throw it out.

I genuinely have no idea how to log this.
