Hi Jimm-V

Thanks so much for your kind post and help.

So If I understood well, the following is what their mutations are:

Chick 1 - Opaline Greywing blue
Chick 2 & 3 - Opaline Greywing green

I guess that the types of green on the second and third chick could be deduced at a later stage when I have photos of their backs as they are now, fully grown and flying around. I can't put my finger on the type of blue on the first chick...internet searches give you the same blue colour name for different hues of blue so they left me a bit perplexed. I shall research a bit more even on the genetics guidelines on this forum.

Thanks for your wishes on my studies. I am going to major in English (lit & linguistics).

Thanks again for your help.
