help with color genetics

[stephanie1992]

I have two cochins togeather in a breeding pen.
No chicken can get in or out without me taking them out or putting them in
well one chick hatched today but isnt doing well


Father is white
Mother is buff


Chick is blackish-Brown face-White wing tips



How did that happen???

i thought it would be white

One possibility is that the male is only carrying one copy of the allele for white. That white allele (I) is dominant so he is white. But the chick may have inherited the other allele which could be wild type (i+) and that combined with the female's genetics gave you the coloring of your new chick. I don't know if white cochins are based on dominant white or recessive white or maybe just silver? But in any event the female had "no white" to contribute to the genetic formula.
