The Silver Laced Wyandotte hens are producing sexlink chicks: sons look like that, daughters are colored about like a Buckeye or like a Speckled Sussex but without the speckles.
The Silver gene turns red/gold into white. The Silver Laced Wyandotte hen has the Silver gene, and so does the chick in the photo.
Silver is a sex-linked gene, located on the Z sex chromosome. A rooster has chromosomes ZZ, a hen has ZW. So the Silver hen gives her Z chromosome (with silver) to every one of her sons, and her W chromosome to her daughters (makes them female, but does not have any effect on their color.)
