Failed Chocobo dyeing

This is was happened:

i gained 180 O'Ghomoro Berries from 5 seeds i planted in my FC garden, wanted a Ink Blue chocobo, that's why so many berries, so I stabled it and started to feed him with 100 berries. Obviously after the first 3 berries it already started to say my chocobo was beginning to grow new feathers, and it kept repeating that for the last 97 berries. After 20 minutes i was done, left it in that stable and went to bed. Woke up 10 hours later and my chocobo was still there, happy, fat and yellow as a lemon. Started to worry about it and thought that maybe it needed more time because of all those berries... i left it there for 5 more hours, got back and it was still yellow... waited 4 more hours and that chicken was still yellow as a canary. So after 19 hours i took him out to see if maybe it would suddenly change out of the stable... and of course it didn't, its colour was still Desert Yellow.

I reported the bug in game and contacted the GM who told me to post the issue here.

Wait, you feed 100 berries in one go? WHAT!?

Well, feeding him 100 won't have made more difference than feeding the initial 3... but that it remained Desert Yellow when it was already Desert Yellow to begin with IS odd.

Well, i read around that you need 85 O'Ghomoro Berries to obtain the Royal Blue so i supposed you need at least 100 berries for the Ink Blue... XD
