At what age(s) are colors/varieties noticeable?

[Pineapple]

I am going to pick out some chicks which will be hatching in 3-4 weeks. I can wait a couple weeks if I need to (it's a long drive) but once I get there is there any way to tell what colors/varieties/gender individual birds are as 2-week olds?

As 4-week olds?

The person doing the hatching has said there are "all kinds of varieties" in the mix .Just wondering. I've done some searching on this forum but as always the "sticky" threads are too massive to actually find information in. Thanks, y'all!

Experienced breeders can sometimes tell the color as soon as the chick is dry. You might be able to find pictures ow chicks of the different colors. At 2 weeks, I think you'll be able to tell most colors apart, but I'll have to admit that assumption comes from pictures - I've never actually seen a real-life coturnix ^^. I think 2-3 weeks is the earliest you can begin to tell the sexes apart, but even then it's only wild colored birds you stand a chance of sexing at that age, most other colors require you to wait till they are 5-6 weeks old and start crowing, producing foam and possibly laying.
