what breed are these 6 month chickens

[beszchick]

and these two roosters

 

[BantamLover21]

The hens all look like Cochin mixes to me, unless they have pea combs, in which case I'd think they were Brahma mixes. The mostly white rooster is probably a Delaware or Delaware mix. The black/white barred rooster is most likely a Barred Rock or Cuckoo Marans mix.

The hens appear to me to have pea combs which would make them Brahma mixes. The white rooster is a Delaware mix, and the barred rooster is probably a Barred Rock mix.
