When will I know gender?

They're too old for that, at 2 weeks old...
Also, that only works on very specific breeds and crosses... none of these fall into that.

Do you know which breeds it works on? It worked on my French Cuckoo Marans

So I know he (I’m just gonna go ahead and say he) is only 3 weeks old, but I’m pretty sure I have a cockerel. His comb is so much bigger than any other chick. I’ll update in 2-3 weeks.
