Probably the wrong board, probably there's a topic already...so my apologies in advance.

I want a dalamud red chocobo.
I know how many and which fruits to feed him.
My question is:
Can I feed him ALL the fruits at once, regardless of the "growing new feathers" message?
If not, how do I do it exactly? What if I run out of apples and haven't gotten the message, do I continue with the next fruit?
I really just don't get it...
