If it's a specific pair you want to mate, I hope he thinks she is one of his women. Sometimes they won't do it with a gal that isn't 'theirs.'
You can try to separate them, observe behavior, see if he 'gets it' and 'gets it on' with them for a few days or so. Soon as you see the lovin' happening, get the next eggs. I will take them each into the incubator soon as it's laid, date and mark them with my customary 'sun' on one side, 'moon' on the other (and the proposed hatch date) with a sharpie marker (I don't wash the eggs). Sure, it makes for a few days of hatching but I suppose you could wait a few days with the eggs on the counter, like someone else suggested, at room temp. But if you're batoring them anyway, a few days of hatching isn't that big a deal.
