Correction to the previous post.

I shouldn't say that there are 2 type of dinosaur look like chicken that laid chicken egg.

The truth is that, there are 2 type of birds look like chicken at dinosaur age laid chicken egg. They are Red Junglefowl and Grey Junglefowl. Both of them really look like chicken.

This is red junglefowl or the other name, gallus gallus. It is often believed as the ancestor of chicken.



This is grey junglefowl.


In short, chicken is the hybrid bird by red junglefowl and grey junglefowl.
