I don't know about the first two but the last one looks like my Rhode Island Red. How old are they? They're adorable.
The second one is a plymouth rock ?(do they come in Bantam) and the third is a RIR or a production red (a roo maybe look at the comb). The first I don't know. from California
The first looks like my cochin barred rocks I got 3 yrs ago...maybe the same in the second pic ,but can't tell because the legs aren't showing . Third pic looks like an RIR....if it has black tail feathers it would be a production RIR .....forgot to look at the tail !JMO . There are others on here who are better at picking breeds....so I'll pass it off to them .
I have had them for almost 4 weeks. I bought them at TSC, but I don't know how old they were when I bought them. I am guessing maybe 6 weeks old? Raising chickens is addicting!!!!!!!!!!!
im going to go with every1 else and say barred cochin becaus eof feather foots and bantam size, then a production red for the last chicks as if you look in tail are it has dark black feathers, well thats what the pic makes it look like
#2 barred rock #3 RIR, production red, or maybe a new hampshire red, since it seems kind of light (definitely a roo) 6 weeks is a pretty good guess - they might be just a little bit younger than that - maybe 5 weeks? It's not a very good picture, but here's my 7-8 week old production red (you can see the black coming in on her tail). Notice how much bigger the comb is on your chick even though it's younger. Here's a pic of my old barred rock pullet when she was 7-8 weeks old:
