making turkey stock for the first time, leave it uncovered as it boils or cover to simmer

I bring the bones alone to a boil and skim off all of the grey foam. Then I add the veggies & turn down to a bare simmer. It’s supposed to produce a clearer result.

i did boil then simmered. why not boil?i did not cover the pot tho. thanks for commenting.

Uncovered but just a very low simmer, don’t boil

Let just barely simmer & leAve it uncovered.
