it means you will need 2 copies of the white gene for solid whit birds and since both the mille and golden have white in them you might end up with some white birds but i doubt that i'm thinking that they shoud have at least a little bit of color to them...as long as they aren't solid yellow/white as chicks they should have color to themTomorrow I'm setting eggs that I've collected from my D'Uccle hens. They will be Mille Fleur x Bantam White Langshan, and Golden Necked X Bantam White Langshan. I was told the Langshans white was recessive, which means zip to me. Any guesses on coloring (in English please)?LOL!!
