This should possibly be moved to the Breeding IRN forum section.
Edit: your bubs are looking great, good to see it going well.
On a basic level, the genetic calculator works by selecting the correct mutation checkbox for the parent birds.
Grey (the visual grey mutation) is not a stand alone gene. Visual grey is actually choosing the options Grey and Blue, in gencalc.
Visual colours on the left, splits (non visual) on the right.
sf = Single factor, df = double factor... a regular Grey IRN is sf Grey + blue both in the visual column.
Turquoise Blue is actually Turquoise(parblue) as well as split to blue.
Hope this helps, its just a general rundown.
Below is a screenshot of what a Grey cock bird to a Turquoise Blue hen should look like. 1.0 = Cock, 0.1 = Hen. Then hit "Generate" when are done selecting the mutation values required.
