I know males come out white when you get sex link babies. They said that they were Tetra Tint. They said al the chicks in that bin were female. (Hopefully) I hate giving chickens away, haha. As for the White Rock chicks. I think they had those in the right bin. I compared the Cornish with the white rocks and the Cornish were bulkier. So, I think I got what I needed.The darker ones are female gold comets. As for the light ones, they could be one of many breeds that start off light yellow. They COULD also be male gold comets (females are caramel colored, males are yellow).
