Question:
my mother and i have a bet going on.
when a chicken lays an egg, is the shell soft
when it comes out , or is it already hard?
I say that the shell is soft and that it hardens
as the air hits it. Mom says that it is already
hard as it comes out. Who is right?
Replies:
Mom wins!
I grew up on a farm...for chickens the shell is already hard as the hen is
laying the egg. Perhaps in other bird species this might be true.
Occasionally an egg is layed without a shell at all! In most turtles and
snakes the eggs are never hard.
