How old are my hens?

[Queen of Chickens]

Hi everyone
I just recently got these hens, but the owner didn't know their age, since he had a lot. They're not laying yet... how old do you think they are and how long till they'll start laying?
(3rd picture is 20 weeks). The breeds are Brahmas, and Olive Eggers. Fourth picture is a barnyard mix.

1,2 and 5 are young pullets. I'd guess 4 to 4.5 months.

4 looks older. 6 months, maybe, although that is just a guess. If she's not laying now she soon will be.

They lay in their own time. 25 to 30 weeks is normal, but later isn't uncommon.

I think you will get eggs from the young ones within a month.
