Male Or Female?

[Sebright18]

After incubating 12 eggs under my broody hen, only 3 bantam chicks hatched, I am pleased with them even though only 3 hatched. They are very sweet and today they are 3 weeks old today and i would really like to no whether they are female or male.



So how do you tell if they are a Cockerel or a Hen


Thanks

My little bantam chick (Blue Old English/Brown Leghorn cross) started crowing around 3 weeks old. I was in shock as I had never seen a chick crow. (other large breeds don't start to crow this early, actually most don't until they are around 4-6 months old).
Another really good clue is that the comb on a male starts to grow a lot faster.
here is a link to some other ways to make an educated guess....
