When four birds are firmly perched around you expecting you to scratch their head??
Piper, Shade, Zuri and Pixel were not willing to share; Zuri and Piper were particularly insistent and pushy, which meant that I tended to Shade and Pixel first (rewarding the better behaved first). But while everyone was happy when it was their turn in the rotational circle, no one wanted their turn to end.
I guess I need to grow another set of hands.
