Not a genetic expert, but I believe it's actually the hen that is the heterogametic sex in chickens, the opposite of humans. So I think its actually the female (or the egg) that determines the sex, not the male (sperm). Here's an easy-to-read link about the ZW chromosome...

Here's the Chick X:
Here's Chick X again, with Salmon pullet in background:

Finally, the Salmon pullett again.
In case it wasn't clear, these all came from the same breeder, all hatched at the same time. From Boulanger and Buffington lines...
All,
It's identical to the pullett in every way except coloring. Muff, beard, five toes, smaller comb, shorter tail feathers. I have been raising chickens for some time and am fairly educated, so I'm reasonably certain its a faverolles. Could it be mahogany?
I need your educated help. About 6 weeks ago I hatched out what was supposed to be Salmon Faverolles eggs. I got four chicks and anxiously waited to see what sex they would be, believing that coloring would be the answer. Often I am able to tell by the emergence of tail feathers, with pullets...
