Of course, np. So, I would take things slow around her, make sure you're not rushing away which can seem like running. If you need to walk sideways, that's fine. Just make sure you are deliberate and certain before everything you do, because that puts a lot of confidence into your body language.
Imagine your dad coming in the house for dinner after a long days work... he's thinking "hungry. eat food. yum." (or at least that's how I imagine men think) and that rather singular intent injects a lot of certitude and confidence into the body language.
You are the immovable rock. She must flex to your wishes, not the other way around.
She doesn't need to be across the field before you walk away, but she shouldn't be close to your heels either. You know her best and it's your instincts in the moment that will tell you whether she's too close, if she's looking at you with intent or not.
If she's gotten up on the roost while you're cleaning, stop and make her get down. If she's close and you need to go get a hammer, walk through her space expecting her to yield, and do something of an arc to go get it.
Sorry if this is somewhat vague but it's hard to describe movement, for me anyway.
P.S. she really looks like a hen to me. Training roosters doesn't work IMHO. But maybe a hen has a chance to learn without all that testosterone interfering.
