I took a peak under my pond cover and noticed 1 of my 6 Koi was dead.
It is laying at the bottom of the pond near where the other fish are.
Should I get it out or just leave it? I am a little concerned that
poking a net down there is going to really disturb the other Koi. Will
leaving the dead fish have a negative impact on the water quality (pond
is 500 gallons)? I am in Chicago and the water temp is around 40 now.

The net won't disturb them nearly as much as a rotting fish (and, yes, it'll
still rot at 40F...just slower than at 80F).
