1 & 2 have a fair bit of white--I'm going to guess not Barnevelder.
6, 7, and I think 8 appear to have a lot more feathers than 3, 4, 5. I wonder if that's a breed difference? But 7 & 8 might easily be Barnevelders, while 6 is one of the pale chicks, so likely not a Barnevelder.
Sorry, I'm just going to give up for now
Maybe someone else will pop in with some better ideas, or maybe you'll just have to guess and possibly swap chicks around later.
