She is turning them
It's what chickens do .... the debate isn't around what chickens do, it's more what we do in an artificial environment.
Anecdotal articles aside I have yet to see any properly controlled and verified study suggest that eggs should not be turned. There are many that suggest that regular turning increases hatch rates.
I think this simple fact is left open to discussion mainly because quite a lot (maybe 50%) of eggs will hatch whether they are turned or not.
Surely the point of discussing incubation, and advising each other should be aimed at maximising hatch rates, not settling for something less.
