Really easy way to sex 3 week old yokohama bantam chicks

[Nemmi123]

After giving myself a major headache scouring the internet and getting nowhere. I thought I would share what I've learnt with others that are giving themselves headaches over the same thing. I've attached a couple of photos of my adult Yokohama bantams. To show the clear colour difference between the brown adult females and the red adult males. Which as chicks are frustratingly all brown with no clear difference between the sexes. UNLESS you know what to look for. So I added the last two photos showing the clear differences between the sexes from 3 weeks of age. If I've helped one person, it was worth writing this post

I get what I’m seeing on their backs but not so sure about where you’re holding them showing faces. Combs don’t look much different.

Feathering on the breasts/chests is the determining factor. Pullets will have the wild type brown feathering while cockerels will be darker and eventually black.

That depends on what color they are. I could have used that on my Onagadori, but they are 10 weeks old now.

Quite evident that the OP is talking about Black/Red birds. Comb size is never a 100% definitive indicator of gender.

It's not there combs, look again at their breasts. The female has much paler breast feathers. As the males breast will eventually be black
