If your cock was split to blue ino (rather than just lutino) and your hen was split to blue, you could get blue and green cocks, and blue, green, Lutino and albino hens.
Blue is recessive, so it needs to be present in both male and female, whether visually or split to (unseen), to get VISUALLY blue chicks.
IE, Green/blue cock x Green/blue hen = green, green/blue and blue cocks and hens
Or Blue cock x Blue hen = 100% blue chicks
or Blue cock x Grey hen (greys(sf)blue) = grey and blue cocks and hens
or Grey cock x Blue hen = grey and blue chicks
Those are just using very basic mutations. Another example where you can get blue chicks is:
Blue violet (sf) cock x blue hen = blue and blue violet (sf) in both cocks and hens.
So if your cock and hen are not both split to blue, they won't give you any blue chicks. You could test breed your green hen with a blue series cock to see if she is split to blue, but it could take a couple of breeding seasons to prove this. If your cock is split only to lutino (yellow), I don't think you can pair him to anything that will give you blue, but I could be wrong on that....I've tried a heap of different combo's on the GenCalc and haven't been able to come up with blue offspring for him if he's just green split lutino. You could test breed him to a blue hen to find out if he is split to blue as well, but again, it's a time factor.
If you really want to breed blue babies, probably best to invest in another pair that come from the blue series, eg bluexblue, greyxblue, greyxalbino, bluexalbino, bluexgreen/blue, bluex(sf)violet etc, etc.
Hope this helps
