Speckled Sussex, Welsummer, something else?

[Farmchikshep]

I bought these 3 chicks from a guy who hatched his own eggs and also buys eggs from hatchery and hatched them. They are all supposed to be speckled Sussex, and the guy spent a good 15 minutes staring into his brooder trying to figure out which chicks were speckled Sussex. He did have a list of breeds but has taken it down now that he’s done hatching. He then gave me these 3 and said he was pretty sure they were speckled Sussex. I’m not so sure. I think the one is with white on its chest but the other 2 are growing mostly black feathers. Does anyone know what breed they could be?

The one with white on the chest looks like my 5 week Speckled Sussex. The other two don't look like my Welsummer pullet though

Hmmm, the first is maybe a Barnevelder cockerel. The one with white is your Sussex.
