Please help me find find out the breed of these ladies

Hi Everyone, I recently inherited and some how became the mother of these 6 lovely ladies but now I am cramming to learn everything I can. Can anyone tell me what kind of breed they are and about how old they are? I have had them for almost three weeks now and can't seem to find any pictures that could help decipher this so now I'm hoping you guys can. Thanks so much!

I can also get better pictures if needed.

The black and white birds are most likely barred rocks, the reddish/brown birds are production reds, and the other two may very well be EE. Good luck with your new little flock.

Thank you so much! The black ones I kind of thought were that breed but the more I read, the more confused I got

! Would you have any idea how old they could possibly be??
