Feathered feet...could it be a Cochin? How many toes do they have?
Did you order them from a hatchery? If so, which one? Might help to know what they offer as far as bantam breeds.
With 4 toes that rules out Silkies so maybe they are Cochin bantams...(I love my Cochin bantams! lol so that's what I think of first) Maybe someone else will reply with some other ideas
And at TSC they just label theirs as "bantams". They get theirs from a hatchery, but I don't know which hatchery. Hmmm... I'll have to think some more about possibilities of breed.
