Not Sure what my Chickens are? Maybe Wyandotte?

[6ChicksandaDog]

Hi I'm new to backyard chickens. And I got 6 from our local tractor supply. I definalty got 2 Black Australorp and 4 that I'm not to sure what they are. Based on my research I think they are the blue laced wyandotte. They are great and these 4 are the most curious little creatures. We've had them since April so they have grown like weeds. Here are some pictures that I just took yesterday. Any help with identifying what kind of chickens these are will be much apprecited.

Also if you need better pictures they love there picture being taken so I can definalty get them.
Thanks again Everyone.

The last two look to be Speckled Sussex. What color legs do the first two have? None are wyandottes.

The one in the first picture that is primarly dark brown feathering has yellow legs, we call her road runner.
Thanks for your help!

They could be welsummers or partridge rocks I honestly don't know.

In the first pic you have 1 Partridge Rock and 1 PR/SS mix.
2nd & 3rd are both SS.

I have both breeds, you'll love each type.
