only birds and and some animals (i think just a platypus) can lay eggs. so yeah, it's impossible. maybe in the far future they will invent a way for humans to lay eggs... but i don't see the need. And your friend is crazy. you should get her checked.
also humans cant have chickens. only other humans.
Not possible unless she is like a freaking half bird or something.
who put the egg in her vagina?
... She needs help if she wants to do that...
Alright I'm asking this for a friend. I know this girl who says she wants to lay an egg. Now I know this sounds crazy, but I told her to swallow a whole egg and see what happens. She said she did, and she pooped egg shells! How can I make this egg come out of her vagina? And how can a chicken hatch from that egg?
