Moth playing chicken(s)?!

From time to time the chookies will tap on the glass of the front sliding door, or the window behind my usual seat at the computer. Today they tapped so firmly and persistently that I got up to investigate.

There were three of them, jostling for space and pecking at a small moth. Where was the moth? On my side of the glass. Did the chookies give up. No. Not till I chased them off.

The moth is the white speck you can see in the smaller photo - and is fluttering just below the beak of the middle chook in the larger pic.
