You nest sex they work it by the parents.

If they know what the parent genetics are they can tell what the babies will be.

Say the parents where male lutino and female blue (this is just an example).

All babies that are yellow are female and all babaies that are blue are male.

Not correct at all. :)

the male offspring is green. the male offspring can be blue then the father is split for blue but there is still green male offspring.

no. the males are green/blue/lutino and the females are lutino/blue.
lutino is a sexlinked mutation.

No worries.

As an exmaple to nest sex =
Male blue cinnimon (light blue) X Female Blue
1.0 blue cinnamon
x 0.1 blue
% from all 1.0
100.0% 1.0 blue /cinnamon
% from all 0.1
100.0% 0.1 blue cinnamon

So any visual cinnamon babies would be female.

In your case you would either need to wait till they mature or do a DNA test.
