Chocobo Egg (Somewhat Warm)  

In addition to these dropping from ISNM I just got one from breeding my bird w/ another.
Bird 1: Rainbowthunder (female)
Str: Substandard
End: Substandard
Other: Poor
Abilities: None

Bird 2: Can't remember name ... (male)
Str: Substandard
End: Substandard
Other: Poor
Abilities: None

Matchmaking method: Gourmet Food
Result was a Somewhat warm egg...

My LS member whom i mated birds with recieved a Bit warm egg with same birds and the 'Walk' method. Dunno if this will help or not but was easier than doing a isnm lol. Hope it helps.
