Hey! I have a few D'uccle chicks at 6 weeks (I have 6). All but one of them are mille fluer and can clearly be comb sexed, but my one porcelain I'm not sure about. Thanks for any help! And I'm going to put in pic of my mille fleurs for good measure Rooster: Hen: I'm betting rooster because of the size of the comb but it's still alot paler and smaller than the millie roosters. Thanks! P.S sorry for misspelling it in the title, auto-correct got me!
