I know its an individualo thing, but for those who weaned your own birds or were involved with the process, at what age did your birds (especially amazons) start to eat on their own and finish weaning?

Seemingly they start eating on their own at about 10 weeks old - in my limited experienced with them but of course not enough to sustain themselves.

My chart here says they wean about 14-18 weeks - depending on the type of Amazon.
