identifying female turquiosine

It is generally stated that female turquoisine looks duller and lacks red bars in their wings. In my case when three babies came out from the nest two had distinct red bars in their wings one slightly duller had no red bars.

After two months the duller one had shown two/three red spots at their wings but it had white lores ( the region between eyes and the bill on the side of the bird head). However the other two having red bars have no whiter lores. Can any confirm that the slightly duller one is a female?
