Hippalektryon

Hippalektryons are endangered species of a type of Monster. They are kept at the Triple G Ranch. When their eggs are laid every year, they are made into omelets by Geryon. Geyron and Eurytion hint that hippalektryon omelets taste better.

Appearance
Hippalektryons are half chicken, half horse.

The Battle of the Labyrinth
Hippalektryons were seen by Percy, Annabeth, Grover and Nico when Geryon were showing Triple G Ranch on his Moo-mobile, with Annabeth exclaiming that she thought they were extinct.
