Alectryomancy is a form of divination using one or more birds, most preferably a white rooster or cockerel, which peck at scattered grain such as wheat. The process involves the following steps:

• The diviner scatters grains randomly on the ground.
• The bird(s) are allowed to peck at the grains.
• Once the bird(s) have finished pecking, the diviner interprets the patterns left on the ground.

In an alternative method, the bird is tethered in the center of a circle marked with the alphabet around the perimeter. Each letter of the alphabet has a piece of grain associated with it. The process includes:

• The observer records each letter that the bird pecks at.
• Each grain is replaced after the bird eats it, allowing for letters to be repeated.
• The sequence of letters recorded is interpreted as a message.

Alectryomancy is related to:

• Ouija: Both involve random selection of letters.
• Gyromancy: Involves random selection of letters from a circle.
• Orniscopy: Divination by the movements of birds.

Another form of divination using birds is Ornithomancy.
