I think the ones with stripes are the ee's and I may also have 2 mottled cochins. all have feathered feet except for the chicks with stripes. are they silkies ?
the black and white chick in the first picture looks like your mottled cochin
if they have feathered feet and 5 toes and black legs, silkie
if the same as above but yellow legs than they might be salmon favorells or sultans
I see white & buff & a black silkie, 2 mottled cochin bantams, 2 possible welsummer or brown leghorn (1 may be a speckled sussex, can't see the legs or face) and an EE
