Feather sexing cochins?

[Shugercube]

Hey everyone! So I heard you can feather sex Cochins pretty early, is this true? I have a bunch of 10-day olds and if google (and my interpretation) is correct, they're all male except for 2

Would be very interested to know if this is an accurate sexing method. If so, I'll gladly post some pics for confirmation!

I've never heard that Cochins can be wing sexed. Perhaps some strains have been selected for this trait. Hopefully someone with more knowledge will respond.

Hopefully you're right and this is all bs because lord knows I don't need any more boys (I do have a plan to accommodate any and all roos I may end up with, I just would really love more hens )

It is not accurate at all. I've hatched many Cochin bantams over the past few years and the only part of that chart that worked in sexing them is the 5-week comb thing at the end. Feathering speed depends heavily on the line and sometimes the individual within the line; my Reds, for example, all feather like this says pullets do, even when they're cockerels, while my BBSs tend to feather like this claims cockerels do, even when they're pullets. The boys generally grow their combs in super early, though, making them pretty obvious even by 4 weeks of age in some cases. It's safest to wait until about 6 weeks for accurate sexing on most chicks, however.

Found this on another thread.

Definitely not accurate. That same pic surfaces every so often. I wish it would disappear altogether.

At around 4-5 most boys will be evident by comb development.
