Would color of young reflect gender

[maine123]

I have heard of sometimes the color of a bar would tell the gender of a bird (depending on the parents.)

I have a pair a (cock)pure white homer, and a (hen)opal bar (thats what the guy told me.)

The young resulted in a grizzle looking bard pigeon, and an almost all white one with some tan spots on it's neck.

Just wondering if it would be possible to tell the gender of the young?

THanks, if you need pics I could take some.
