If your eggs came from a RIR rooster and a white hen with the silver gene, then the females would be redish fluff, and the males would be yellowish or whiteish if they were sex-link chickens. Do you think you have all males?
or
if the female was white, and lacking the sliver gene, then they couldn't be color sexed at hatching. I think this was already stated.
And..... doesn't the egg color come from the hen? And if the hen was leghorn, wouldn't the eggs be white? If you were to do some searches here in the box on the upper right hand side of the screen you would probably find some amazing information on chicken genetics. People post here who have TONs of knowledge on the subject.
Let us know once you find out.
