Yum! Tasty.

Definition: Amniotic eggs are produced by birds, reptiles, and certain mammals. In amniotic eggs the embryo develops inside a amnion. These organisms develop inside a calcium based or leathery shell instead of it's mother.

What the specimen is: These are brown chicken eggs.

Where we found them: These are regular store bought eggs that were found in Sarah's kitchen.

How they relate to amniotic eggs: Female chickens produce their young inside amniotic eggs. Instead of completing development inside of their mother, the embryos must complete a 3 week incubation period before hatching.
