Serama Bantam Hens 5 months old?

[Cakemom4]

Hi! I have adopted 2 rooster serama bantams from a lady that did not want to keep anymore boys, they are so awesome! I know they are 5 months old, but we also adopted 2 hens as well from someone else and the guy said they were about 5 months old. They have not layed any eggs yet, and I was wondering if there was a way to see "about" how old they might be...I'm hoping they are young like he said and not older girls since we would like to have a few babies The roosters are right there with them and I have not noticed the hens "squatting" when they get near, I don't know if that is something to watch out for, I know with our GLW they have been doing the squat when we walk by lol.
Thanks!

Sometimes hens will lay later, depending on several factors. If they are squatting that is a good sign.
