Ivriga unga tuppar

He proposes...

The cock shows his interest for the hens on the arena by performing his display, which includes sounds and motions. He extends his neck and spreads out his large tail in front of her.

...but she hesitates

But she walks away uninterested! A hen willing to mate lies down on the ground and lowers her wings. 

The hen chooses

The hen probably disliked the male's way of courting her. Maybe he was too eager and approached her before she signalled that she is ready to mate. Young cocks are often too quick, while the older are calmer and await the hen.
