Question on Breeding/sexing Cochins

[whatdaflockfarm]

I've just started to breed Cochins. I have blue and black in my breeding flock. I understand that the genetics of this flock will produce blue, black, and splash varieties. I have only found 1 hatchery that sexes day old Cochins and have given up on the thought of being able to do so myself since they hire "experts" which I am NOT. However; from what I have come across, Cochins are fairly easy to sex by about 2-4 weeks of age by appearance. Males having noticeable combs and females having little to nothing. I'd like to sex them as accurately as possible. Any comments or tips would be appreciated.

My first hatch is in the incubator on day 6. I will post pics when possible.

With two of my most recent cochins, I was unsure on their sex until about 10 weeks old when they suddenly sprouted combs and started getting stringy saddle feathers. The rest followed the typical pattern you described. So, I don't think it's 100% (but then again, neither is vent sexing).

Nothing's 100%, if only....

Thanks for your input, we'll have to see how things go.
