Sex of this adult yellow back?

[elferoz777]

HI all

I need some adivce from a goudlian guru to help sex the bird below.

This little one has been sitting on eggs and has recently began feeding the young.

I am thinking it was a hen but recently I am not so sure.

Whats are your thoughts?

I am yet to find the bird it is paired with but all the young seem light so I am thinking it is my rogue aussie yellow or single factor. . .though this theory will change based on the sex of this bird.

Thanks

Compared to the other yellow backs this one is significantly better coloured in the breast which is why I was not sure
