Quote: a laced bird is columbian + pattern gene + melanizing gene. so yeah you could get mille fleurs, but the pattern and melanizing genes may cause a 'dirty' appearance to the pattern.
Nancy, You know I talk to Annamay a lot also, and she's always telling me that as long as I have Tango, even though I'm not breeding Mille Fleurs any more, I should try her in with my Golden Laced to see what I get. Annamay loves genetics, and is not afraid to put things together with similar genetics and patterns to see if it helps one or the other.
What you have to remember is that, with maybe the exception of Lynne's because she has a closed flock, no one can tell you exactly what the genetic background of their Mille Fleurs are going back at least 5 full generations. Pretty much the same is true with all the (bantam) Golden Laced running around. None of us have properly laced female Golden Laced, with full, complete lacing through the back and saddle, which means none of us have "genetically" pure Golden Laced.
So crossing Mille Fleur and Golden Laced is basically a crap shoot, IMHO. Always worth a try, if your birds have good type, and you have the room to house them and the money to feed them. I would not bother trying if your birds don't even have good type to begin with.
