I have 2 females like that. But only one of them is as bad as you said and I’m hesitant to pair her because of the possibility of injuring my male. But the the other one has been acting slightly more food oriented this season. Not sure why. One idea, what size is she? If she’s smaller she might want more material to build the eggs while larger ones may already have most of the mass. This is just a theory though. I would love to know how pairing her goes and how this turns out!
