How to sex my Lutino/Cinnamon Cockatiel

Hi. I'm new here and have recently gotten my first lutino/cinnamon cockatiel.
Do I call this a split? I know VERY little about tiel genetics. :?
I have four other tiels, including a pair of common greys, one other common grey, and a pearl/pied hen.

I'm trying to work out if my new addition is a he or a she. It's around 3 months old with bright orange cheek patches. The wings have the cinnamon markings, and have no banding, and there is only one tail feather with any grey on it at all. The others are all lemon/yellow.
S/he doesn't seem to call very much and is gentle.
Is there any other way of knowing if he's a he or not, or do I just need to wait and see what happens?

 

Lutino tiels can not be visually sexed but since he/she is split is there any barring on the undersie of her tail feathers. Tailbarring indicates a female no barring suggests male but since there is lutino it will be hard to tell the sex.

Do you have any pictures of the new bird..

With lutino's you would not see any barring on the tail but a cinnamon you would.

I have normal greys, Cinnamon, Cinnamon pieds and grey pieds.

Here is a picture of a cinnamon/lutino.

I have been given this webiste its about wing spottin it gives information on the different mutations and sexes.

Hopefully this will help you out.
Also male cockatiels are very vocal the females are more quiet and reserved in there personality.
