Mama, I don't want to eat animals. An egg has an animal inside.
Actually what is in that egg would never have become a chick because the daddy hen didn't put his "didi" in the mama hen and fertilise the egg.
He looked very thoughtful about that. It is a weird one. I find it hard to comprehend myself.
Then why does she lay an egg?
I don't know (thinking... but I will find out).
Do people eat eggs with chickens in them.
Yes, in the Philippines they eat something called balut. The egg is full of the chick.
Does it have feathers and everything?
More like fluff they haven't turned into proper feathers yet.
I wouldn't want to eat that.
I know, because you don't want to eat animals, but if you do eat chicken then eating balut is the same thing. It's just that balut is smaller and still in the egg.
That's wrong..
Why?
Because it is just a baby and it hasn't had any life yet.

I did a little digging:

"Roosters have needle-like penises and after a hen lays an egg the rooster sits on top of the hard eggs and penetrates them with their 'needle.' The egg easily seals over the tiny hole after a day or two."

Really? But that doesn't sound credible. But maybe? I read it on the internet. People wouldn't want to deceive us by writing something that wasn't actually true would they? No. I cannot believe this is how it happens except in the minds of those who believe that humans sprouted fully-formed in our current state, along with all other animal "kinds". Or in the world where babies are found in cabbage patches. Thankfully, with the help of the BBC and various animal documentaries – including a very interesting one of elephants mating(!) – and some strange, and often uncomfortable, discussions with K he understands (roughly) how babies are made and I think he would see that it's not like this. A rooster with a diamond sharp penis running around drilling eggs.

This would seem more likely:

HOW DOES A HEN FERTILIZE AN EGG?

When a rooster mates with a hen, the semen is stored in the oviduct for later use. When she gets ready to lay the egg, a sperm fertilizes the egg before the shell surrounds it. The sperm is viable for about a month in the oviduct.

As to why she would lay "empty" eggs it would seem that she is just getting rid of them. They form, they grow and out they pop.

So he was content to eat an egg on top of his fried rice.
