Help with breeds, complete novice :)

[teach28]

I have 5 chicks - I think 3 are hens, 2 roosters.
They were born May 7th, 2013 - so about 2 months old.

I think these are my two roos.

Any idea what kind they are and what may be going on with the gray one's toes?

Another closer photo of rooster in back:



Now for the girls (well I hope they are all girls):

She has iridescent colored feathers (shining blue in this picture).
Also has hairy legs/feet.




Any help on what kind of breeds these are I would really appreciate!
Thank you!

These are all mixes.

LEFT: Black Sexlink Cross - RIGHT: Barred Rock/Brahma? Cross

Australorp Cross

Maybe not a cross, but Black Sexlink

X2 and with the toes I am not sure but it adds to the cuteness factor,it could have happened during incubation or is a genetic trait

Thank you both! I had a feeling they were probably mixes, but fun nevertheless. Thanks!
