Bobbing their heads at every step. How ridiculous must have that looked if it was the case.

Chickens and many other birds appear to bob their heads because their eyes are fixed in their sockets, so they can’t fix their eyes on a point while moving, but instead have to keep their head still. What looks like bobbing is the bird pushing its head forward and keeping it completely still for a moment while its body catches up. Without keeping its head still, it wouldn’t be able to see much of anything very effectively, prey or predator.
T rex might have been able to move its eyes, in which case it probably wouldn’t have bobbed its head.

The best is when you pick them up and move their bodies around but their little heads stay in the same spot
