how much chicken bones for broth in a 20 qt pot?

Wow, I see so many threads on broth, sorry to add another one.  I just found out my supermarket sells chicken bones!  Score!  Dh will be in the town with the market tomorrow and could buy, but I have no idea how much to buy.  I have made broth many ways but never bought chicken bones.  can someone tell me how much bones to ask Dh to buy?   I have a 20 qt stock pot. Thanks so so so much!

Buy as much as you can use, freeze what you don't use right away, put some in a stock pot and cover with water.  You can do a big batch or a small batch.  Just make sure you use enough water to cover the bones.
