Making Moving Parts on the Chicks

As an added visual, adding moving parts to the individual chickens that jiggle and wiggle as the automaton moves would be a bonus. The wings could be hinged so when the chick 'drops' with the rotation of a egg cam that has been notched, they will flip up with the sudden movement. Rob Ives demonstrates the mechanisms on his website, robives.com Cam Design. Be sure to check out the moving illustrations toward the bottom of the page. He visually explains the motions initiated by the different designs of cams.
