How can I tell what sex my 6 week old chicks are?

[MakittaTonge]

I have 12 baby chicks, all within about a week of each other. 3 full breeds and the rest are crossbreeds. Some of their comes are different shapes and sizes. Is there any way of telling what sex they are apart from looking at the combs? As my 2 pekin hens have different size combs which makes it hard for me to tell. Any help would be appreciated thanks

The color of the comb and wattles is the best indicator, rather than size, because males' combs and wattles can begin to redden as early as 3 weeks, while females' remain very pale until they're near the point of lay.
Other than that, they may begin to get a "rooster-ish" stance and the males may have larger legs than the females, but the most sure way is to tell by the redness of the comb and wattles, since some cockerels take longer to develop those traits.
Perhaps you could post pictures of them and we can try and determine their genders
