Yes Miss they are. I have 1m/1f Blue Birchen (might be some French blood in them, but their feet are mostly clean) . Then I also have 1m/1f/2? French Golden Cuckoos (feather footed). They are sex linked, but I'm second guessing my original guess. I now think the 2 chicks are pullets.
I'd like to actually cross the FGC girls to Sully the BB roo and make some blue sex linked chocolate egg layers. Big problem is I only know the shell color from the 2 chicks. Not sure what color grade Sully came out of. Still though, it's something to do, have fun with, and learn from.

And...
Ayam Cemani roo x Blue Birchen hen
Be some hot fire sex linked chicks.
(AC's can be used for sex linking too)
In that case I may need to buy a couple of the sex linked chocolate egg layers from you when you accomplish that, lol. I saw that eBay lot and drooled over the beautiful Marans and the egg color is to die for.
