Need help in identifying what I have in nest

What do you mean by the cock must be a split to blue?

[Craig52]

To get Silver both parent must be split to blue as it is impossible if one only is to get a silver. As said earlier a silver is two mutations combined, Euro yellow and blue. The yellow mutation makes the blue mutation whitish or light grey.

Nice looking silver I think?

Nice looking bird mate, now to wait till it colours up.

It's very interesting to see the pictures of the babies of different mutations in the same clutch, thank you.

Did they molt into adult plumage? I would like to see their adult colors.

I thought the dark one was a blue back ( No euro yellow + DF blue mutation ) instead of pastel ( male SF sex-linked Euro yellow + DF blue mutation ) , what did it grow into?

I think you hit the genetic lottery.

Totally. What a varied bundle of chicks.

P.S. I rarely see pics of silvers, is it normal for the beads to still have some pale blue as the one pictured above? Or will it turn-out to be ( male ) pastel?
