Ordered 10 Rare Breed Layers assortment from Meyer Hatchery.
Maybe a Silver Lakenvelder and Sicilian Buttercup?
All three of the "Cochins" have feathered feet - two are yellow like one pictured here. The third (top of photo) is larger and had a darker body. I don't have any idea on the chick in the bottom left - except maybe an EE?
Maybe a Golden Campine?
