I have a chick that has the same kind of feather pattern. wonder if Lancelot is a silver laced wyandotte.These are both Silver-Laced Wyandotes. Victoria, on the left, is non-SOP with her single comb. Maria Theresa, on the left, has the correct rose comb.
They're hatchery-grade, not show-breeder birds, but IMO, this is the prettiest of all color patterns for hens.
