Ten Week Old Hens Laying?

[abi24]

My brother is raising 150 white rock meat birds. They were picked up on June 20th (one day old) and yesterday we found three eggs!

Is it possible for chickens that young to lay eggs? Not sure where else they could have come from.

I don't think it's possible for a 10 week old to lay eggs. They are not mature enough at that age.

Sounds like someone is playing a joke on him.
Just snuck them in to yank his chain.
