Welcome back to the forums and congratulations on your chicks!
Your female is a sky blue yellow face type II recessive pied, possibly cinnamon budgie.
Your male is a dominant pied clearwing budgie.
Both of the parents are blue series budgies and so will the chicks. Depending on the blue colour masked by the father, you can get sky blue or cobalt blue chicks, you can also get grey chicks. All of your chicks will be split (carrying the gene in hidden form) for recessive pied and your male chicks will be split for cinnamon. If the father proves to be dominant pied, then you can get some dominant pied and some normal chicks.
You may have some other surprises depending on what genes both parents may be hiding.
Best of luck with your little budgie family!
From your latest photo, I'm noticing the colour on your female is darker than sky blue, she looks almost the same colour as her mate.
By looking at her cheek patches, she doesn't look grey to me. She could be cobalt violet in colour. From the pictures I'm unable to be certain.
