When the humans let you out, run like the wind towards the chickens. It also helps to take a stick with you, just so they know you mean business.
Announce that you are here and will be keeping a strict eye on them.

Stare at them like your life depends on it while watching their every move!
Get to know them. they all have names. it builds a false sense of security for them.
I did have to eventually leave my post and go inside as grandmama said my constant staring and made the chicks nervous! I'm just keeping them in line and perhaps waiting for one to make a break for it!
Love, Janie
