Ah...looks are a bit deceiving. Most of my pictures have them looking bewildered...or in a blur of motion. If you have a digital camera on a tripod, it's a little easier to "catch" them in a pose because odds are if you snap 50+ shots of each chick, one of them will work.
I set up a tripod so the camera was just above table height. The background is a piece of packing newsprint on the table and draped over a styrofoam block to make the "back". These pictures just use an overhead light source.
If I were to do it again, I would probably use some paper that didn't bounce the light as much...to get rid of a little more of the back-light and move the light source a little lower.
