So for everyone who is confused with the controls:
You have to click the screen not necessarily the door when the real chicken is above/in the real door.
There are fake chickens which look like ghosts and fake doors which are also pale.
Sometimes right before the chicken enters the door there comes an x and you have to wait for the real chicken (door 9,21,31,43,53,65,75? etc.).
The hidden badge is in the pause menu.
