I have a pair of Mille Fleur d'Uccle whose eggs sometimes hatch out as Porcelain d'Uccles. I think I've figured out that this means one or both of my adults caries the Lavender gene which is what makes Mille Fleur become Porcelain. So........ if Porcelains hatch will they breed true for Porcelain? If Mille Fleurs hatch will they breed true to Milles if they're mated to their variety? Or will the possibility still happen that the M.F. will hatch a P.?
