Oh, ok! You know I have seen this in an old hen of mine do this. I thought maybe it was neurological or something being so ancient. It never caused her any trouble. But if your girl seems stressed, you might post in our Emergency section.No no the behavior is very quick and thrust like pecking the air obsessively like she is catching imaginary flies there is nothing there but it looks like she is seeing things and trying to catch things all over the room in corners and such!
