Think more better please! Make your answer very acceptable and logical!

See, I found a perfect answer for my questions.
1- Origin hens laid eggs without nest. She did not prepare a nest because she did not know the future.
2- After several days, she found that eggs hatched and chicks came out.
3- She was happy.
4- After long time, she felt that she would lay eggs again.
5- She remembered. So, she made a nest for her chicks.
6- She laid eggs in the nest and incubated them until they hatched.
7- She fed her chicks.
8- And so on until the new behavior became innate.
9- By this way, the behavior passes from hens to chicks till now.

I am brilliant, am I? 
