Actually, that could effect things. It could be that he was the one getting her to eat grit by the little rooster "eat here" dance they do. Also, it's mysterious but quite common that many hens who are the top hen will go through physiological changes when they have to become the 'rooster' of the flock.
Oddly, mine (who was an adult) grew more comb and had two feathers develop more like rooster tail feathers. It's unexplainable since she's fully a hen and nothing but a hen. Or maybe something about not having a rooster caused less of a drive and changed the way her body reacted? Again, a mystery, but I'd keep it in mind.
If she's still passing the eggs, I wouldn't worry terribly about it. When you start to see thin spots in the egg, then I'd be more concerned. But I do think it's worth continuing to experiment in increasing her calcium intake and perhaps slightly lowering her phosphorus.
