Are these chicks really 10 weeks? And what breed are they?

Hey i just picked up some free chicks, they were said to be 10 weeks but dont look it at all and the owner didnt know what breed they are, my guess is brahma because of the legs, if they are can you guys let me know if they look bantam or regular i need to know if i need to add a entire shed to my run for them to sleep in

Here is some pictures

Thinking she's around 4w-6w. Looks like a Buff Brahma.

I agree 4-6ish weeks, but lean more towards the 4ish. I have almost 5 weeks olds and they look very similar in feathering amounts to that one--usually at 6-7 weeks they are fully feathered which means that cute little head wouldn't be so fuzzy
