Randomly I ask how does an egg get its shell? The answer is kind of surprising.

Diagram of the egg factory that is a chicken.

So the other day, I was standing at the stove making scrambled eggs when I wondered, how does a chicken get its shell? It seemed odd to me that a chicken could lay one of these large things every single day and that it could come out in its own package. So I asked Google and found a video that explains it. But here are some facts I also discovered about hens that I find kind of cool.

1) A hen's ovary contains all of the ova it will ever have when its hatched.
2) The ovary begins to convert ova to egg yolks when she is mature.
3) You need the right lighting conditions to get hormones to stimulate ova to develop into yolks.
4) Yolks are released from the ovary into the oviduct when they reach the right size and travel down the oviduct to acquire their whites, membranes, color, and shell.

Anyway, below is a short video that explains how the actual shell takes shape. I thought I'd share it in case any of you out there also wondered how an egg got its shell. If you are one of these curious people, watch and learn. :) It's actually pretty interesting.

Have a great Tuesday.
