We have a new almost 6 week old GCC. We've had him 5 days now and hand feed him out of a dropper. He likes eating nuts daily as well as fresh fruit. After researching food, I think I have decided to order some Tops. At his age, should I get the crumplets or all in one? When should I start weaning him? We do have a millet in a dish in his cage but he hasn't really had much of it.
