#8 is a silver Sebright (I raise them too) Be careful with the Sebrights...they HATE dampness and can be spastic chicks and fragile as chicks...but hardy as adults and LOVELY!
#6 is a Golden Sebright...I know cuz I raise those! Rest with the feather feet look like cochins to me in various colors-tho I am not the person who knows about cochins.
