Theortically, the feather sexing works best with chicks of birds considered fast-feathering. Cochins are considered slow-feathering.
I gave it a try last year - the single and double lengths on the primaries were VERY CLEARLY evident - just like the videos and illustrations show. However, I ended up raising some very gender-confused roos with very feminine names.
I know some say it works with Cochins, but most say it doesn't work.
All I can recommend is this - go ahead and give it a try, but PLEASE BE VERY CAREFUL!! Feather-sexing is best done (so they say), when the chicks are 3 - 4 days old. You can do serious damage handling those tiny bantam wings at that age if you aren't very careful.
