For the first 16 or 17 days, my chocobo was coming up as "seems to be a female", then yesterday, it suddenly became "seems to be a male." Now I have a male chocobo named BeautyFoot. WTF.
I've been on a STR/END path with him/her, but would that cause the gender to change? You can't have a female chocobo who runs like the wind? Maybe all chocobos start out as female? This is my first experience raising a chocobo.
