OK, guys & gals, time for another unusual or interesting word. Today we have:

Alectryomancy

Divination by means of a cock (preferably a white rooster) with grains of corn, usually by recording the letters revealed as the cock eats kernels of corn that cover them.

From the Greek ἀλεκτρυών (alectryon) cock + µαντεία (manteia) divination.
