Ah, a discontented hen, and she wants to make sure you know it. I bet she doesn't go on like that unless you show up. Chickens have individual personalities, just like people, and some tend to be more demanding than others. And they learn to whom to direct their ire.
Have you heard of flock scratch blocks? You can get one at the feed store for very little cash, but it goes a long way toward keeping chickens occupied and content.
You can also hang jumbo carrots and cabbages by screwing in an eye screw into the core and suspending it from something overhead. Chickens spend lots of time pecking away at all of these things, satisfying their urge to hunt and peck at large.
I guarantee if you do this, your hen will quit having so much to complain about.
