How do you summon a Chocobo in ff7?

The player must interact with the Chocobo by the fence in the outside pen. Upon the player's initial passing during Part 1, there are Chocobos already by the fence. After Meteor is summoned Chocobos will only appear by the fence if the player rents stables, catches a Chocobo, and returns it to the Chocobo Farm.
