Are chickens always super easy?

New to chickens but they have been shocking easy. They put themselves to sleep, stay together as they roam the yard to their favorite resting spots. Haven’t tried to fly over the 6’ fence yet.

Do they stay this easy? Or is it like human children where they switch it up on you right when you think you’ve got parenting under control?

Using Omlet coop door. Camera in run and coop. Free range whenever I’m home.

This was all a beginner setup to see if we wanted to commit, and so far we love it.
