The offspring are black feathered because the black feather gene is dominant
An Erminette chicken is a chicken with a gene for black feathers and a gene for white feathers. Since the genes are co-dominant, the Erminette chicken has black and white feathers, rather than one or the other or grey.
An erminette chicken would carry both a black gene and a white gene. The erminette chicken represents the heterozygous phenotype.
Phasianidae, and is classified as Gallus gallus

Assuming black allele exhibits complete dominance and the white allele is recessive, the genotype is Bb.

Both alleles for feather color are dominant.
Black chickens like white chickens and white chickens like black chickens.
A silky black copper chicken.
This cross of a black chicken with a white chicken producing an all black and white speckled offspring is an inheritance known as co-dominant inheritance.
polygenic inheritance

Assuming black allele exhibits complete dominance and the white allele is recessive, the genotype is Bb.
4 offsprings
Both parents were heterozygous (Bb). The offspring would statistically be: BB, Bb, Bb, and bb. All but the bb offspring would be black and the bb would be brown.
