Project 365- Day 66

The baby and her dad went and collected eggs from our new residents this morning.
She loved bringing in the eggs, something she was too little to do the last time we had chickens.
But she didn't want to let go of them.

She asked if she could put the eggs in her room.
She wanted to see the baby chickens.
Luckily she was satisfied with me saying that we can't have babies unless we have a rooster and these were just the plain eggs God gave us for eating.
How would I have explained fertilization to a 2 1/2 year old?
