I will echo Frans ... depends on your experience.
I've had babies shipped here that are only a few days old, but I have raised a few babies.;)
If the breeder is willing to hold one for you, why not let him feed it for awhile?

The color should be chosen based on your preference.
I find the visibility to be comparable with black or silver.
What matches the room better?;)
-Brad
The spurs are visible from day one.
Perhaps you did not notice them before, or you are seeing something different?
How old is the animal? The spurs are very small at hatching ... like a little pimple.
-Brad
I agree with Carlton.
Here is some info (including the "Kitty" site):

The casque will probably always be the way it is and this is somewhat normal, they are all a little different.
I keep big chameleons in 2x2x4 enclosures and male...
Hmmm.
phoenix worm: not a great option (in my opinion)
Super worm: fantastic feeder. (in my opinion)
You're making an interesting choice, absolutely the opposite of what I would do.
-Brad
Again, wouldn't hurt them a bit, I don't worry too much about overfeeding males though.
At about 9 months they seem to start eating less on their own.
You can't pick a wrong answer between the two options.;)
-Brad
Superworms are absolutely recommended.
Extremely easy to gut load, very nutritious and less chitinous than crickets.
Variety is ideal, but superworms can be a big part of the diet.
-Brad
You don't need to put anything on the bottom.
Pinheads will work too ... true pinheads are about the same size as fruit flies.
I had good luck housing them in a screen enclosure with a big hibiscus at 2 to 3 weeks old and I think they would be better off starting that way.
They can live together...
