Also since this was a black skin male over yellow skin female, the chick will be sex linked.
Males will have light skin, yellow/white depending on the crossing. Females will have black skin.
Your's looks like a cockerel by it's skin color.
Black hides many colors, but occasionally have other colors Leak through. (Talking about the Father)
Light Brahmas are Partridge/Columbian, & Silver.
I'm only making a guess at the moment, but your chick maybe incomplete Silver Columbian, or possibly Silver Partridge.
The Genetics Calculator...
I've done White Silkie Roo over Light Brahma hen.
The chick turned out a whitish yellow, & faint stripes, & feathered out Columbian.
If you can post pictures of the chick, & possible fathers that'll be helpful?
