Tell them if you have to listen to it, they can each take 2 jobs off the chore list. If you have to solve it, they can take 3 each. That would be things like washing out the kitchen trash can, cleaning the toilet, vacuuming out the car, pulling weeds, etc. (Not things that are their regular or expected chores but the stuff that no one gets to.)
Tell them if no one's bleeding ,on fire, or sitting in a pile of broken glass, you don't need to be involved. You're not their referee.
