What's the youngest your hens have started laying?

[Shrader]

I have 4 chickens that are just over a year old.
They've been laying for quite a while.
I also have 2 EE chicks that are just over 12 weeks old.
This morning, I got 4 full size eggs, then one tiny brownish/ blue-ish egg.
Is it possible that one of my EEs is laying at 12 weeks?
I can't think of any other way to account for it.
Thanks.

12-14 weeks...tiny we fart eggs, as they were on the grass first time round.

wow that is early! Mine are all just 15 weeks but no eggs yet. I'm hoping by 18 weeks they will lay some eggs

Good luck with yours! Let us know if you find out for sure.
