He'll likely have a single dominant white gene, so about half his offspring will inherit that. And he'll have a single copy of the silver gene, so about half his offspring will be silver and the other half will be red/gold.
As for the hens -
The Salmon faverolle is silver, so most of the offspring from that pairing should be silver. Any red/gold would be female. The muffs/beard, feathered legs, white skin and five toes are all dominant.
The lavender Ameraucana should produce solid black chicks, or white if they get dad's dominant white. All will be split for lavender, but it's recessive and will not express. Muffs/beard, white skin, and pea comb are dominant.
Easter Eggers are anybody's guess. Too many possible variables.
FBCM should produce birchen offspring 50% silver, 50% red/gold. The feathered legs and white skin are dominant.
Light Brahma, like the faverolle, has the potential for sexlinks. Any red/gold chicks would be female. About half the female chicks will be silver, like their brothers, so you will have to wait a few weeks to sex the silver chicks. The pea comb and feathered legs are dominant.
Too many variables for the OE, but all offspring should inherit a Blue gene.
