3 Movement Possibilities

Here are three movement possibilities for my gourd chickens. Each one will make a chick do something different. The round one will be the friction wheel for a horizontal disc so the chick spins, the oval/off-center cam will make a chick peck the ground like an oil derrick, and the sawtooth gear will have a chick jumping up and down and its follower (the rod connecting it) slides up and then bumps down the edge of each pointy tooth.  They are all on the same shaft so as it is turned with a crank, the chicks will all move at the same time.
