[Felis]

Your Chocobo is not a Her, all chocobos are raised in Ishgard and sold to the grand companies. they only sell the males so no one else can breed them.

Only the chocobos who was sold during the 6th astral era are all male.
Ishgard lost the monopol after the calamity and there is also a female chocobo at the chocobo ranch near Gridania.
