|Diagram of the egg factory that is a chicken.|
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.
