Can you fool a hen?

[SarahFair]

I bought a dozen eggs for a $1 off a road side stand and just threw them in the bator not knowing if they were fertile or not..
Out of a dozen 2 hatched.

I have two hens who have never gone broody but Ive seen one of them tuck eggs under herself.
Has anyone ever tried tucking chicks under a hen at night that never went broody?

I'd be afraid to try it with a hen that isn't broody. With a broody, sure I've done it a few times.
