What about circling?Sides are good. So is wing flapping. Standing square is what you don't want to see. At this point I wouldn't give them your back, that's probably what they are waiting for. You should stand square, and up right, and have confident, and they may decide they should behave.
One of my 4.5 month old NN cockerels will circle me.
He starts this behavior by coming near me and acts like he’s picking up grass or something off of the ground.
Then he walks around me keeping his side to me and his head down but he will keep cocking his head and looking up at me sideways.
I watch him closely and he doesn’t drop his wing or shuffle.
I then stamp my foot or move towards him but he only moves away slightly, like a couple of steps.
My instincts tell me he’s sizing me up.
The other one doesn’t do this.
He will come close sometimes but not as much and it’s like he’s not really interested in me just passing by or seeing what I’m doing.
This one dropped a wing and shuffled at me once a few weeks ago.
I chased him far and he’s never done it since.
