You are still getting used to them. Chickens are prey animals too, so sometimes they act unpredictable (bc something might kill them).
Once they begin to lay eggs, they tend to mellow out as well. They can become quite friendly once they hit point of lay (POL). If you have no males (which I wouldn’t recommend for you anyway), then a female will take charge of the flock more or less, but you may be seen as the flock leader.
They will investigate things with their beaks, often people comment that when it’s summer, and they have painted toenails, the chickens will peck their toes. Hanging/flopping shoelaces (or any kind of bird or string) will draw their attention too. So, keep that in mind.
If you want them to steer clear if you on any particular day, just add a plastic grocery bag or two to your ensemble, making sure it can flap in the wind and make noise, and I guarantee they will keep their distance.
