(In response to Clem, Charlie, an Macey wanting to take the chicken's eggs to Clem's room to hatch):

Me: you're not going to be able to hatch those eggs into chicks.

Them: Why not?

Me: What does it take to make a baby?

Macey: Hard work.

Me: Well, yes. And what else?

Clem: A mom.

Me: And?

Charlie: A dad!

Me: Yes. You need a girl for the egg and a boy to fertilize it. And do we have a boy chicken?

Them: No...

Me: So unless we get a rooster, those eggs will always be just eggs. They'll never turn into chickens.

Clem: I could be the dad!

Me: Well, you don't have any fertilizer yet. You're not old enough. And, only a chicken can fertilize a chicken egg. A human can't.

Macey: That makes sense.
