Crowing
I read that when the chick is developing, it develops in the egg with one eye pressed against the shell (the black blob you see when candling), which becomes the nearsighted eye... the one used for foraging. The other eye is farsighted and used for scanning the sky and across the fields for danger. That’s why they tilt their heads in different directions while doing one or the other. Thought that was incredibly awesome!
