I wish I knew. Looks like the darker ones might be RIR or similar...the black and white ones i feel confident saying are barred rock, and the light onees....uh.... i dunno
Ok the white chicks with red in the wings are sex-link roosters.
The buff color ones with pinkish leg and feet I cant see the comb but Id say Orpingtons (if they have a single comb) the barred on i cant see the feet if there yellow barred rock if there white then it could be a maran and the red ones could be RIR's, New Hamps.
But RIR's shouldn't have that black spot on there neck.
They look good though..
