Can you tell me how old these chicks are?

[PotterWatch]

These babies are our first chickens. I have done lots of research, but haven't found anything that can help me figure out how old they are. The "chicken lady" at the feed store where we purchased the chicks was out on vacation and the girl who helped us didn't know their age. She did say that the larger BR (in the first pic)was from an older group of chicks. Anyone able to help me out with this? I would also love it if someone could tell me what breed/mix the buff colored chick is. Thanks so much!

The BR looks to be about 2 or 3 weeks old to me while the others are under two.

I'm sure others will have better estimates.

First picture BR- 2ish weeks.
Other chicks- 10 days or so.

My 3 week old chicks have feathers on their backs and chest. I think they looked like your older BR chick at 2 weeks.

Thanks for the estimates. Anyone have a clue what the buff chick might be?
