I got 12 White Rock chicks from Cackle Hatchery. They are 3 wks. old and I noticed some of them have willow ( greenish yellow ) legs. One chick legs are willow but the toes are pinkish yellow.
They will out grow the greenish colored legs most likely. I got mine from Cackle and theirs were more of a blckish-bluish cast and they lost it when they were older.
