I do not think mottling will cause barring on Db, as it normally affects only the tips of the feathers. Au contraire, most of my red cocks with mo/mo had problems with showing the black band at all. I do not know whether he is Db or Di though(or

I am not trying to breed Tolbunt. My interest in the Db mottled birds is a belief it will produce a better gold and better shaped spangle, hopefully larger with out Ml. Tho it may bring out barring. Seeing the nature of mottling to remove messy marki

I though tolbunt started off as meaning jazzy or messy. That was what I was told. Or maybe they were trying for mottled lace tailed laced all along. I will stick to tricolour I think!

Another odd thing about mottled is how it organises black and gold in an vaguely similar way to Pg. As mottling seldom affects every feather it is easily seen. It shows especially on a semi patterned/messy feather where you get the effect of mottling

We are going full circle and come back to my own questioning website. lol. Put together Db, Ml and Pg with momo and you get mottled spangle. This bird appears to have Mahogany but my experience of it in this project is it enhances green sheen, th

Aren't spangled Orloffs sometimes e^b based? And Tollbunt Polishs? Maybe this posting from Kazjaps which refers to Sedgwick Wyandottes could enlight something? http://www.the-coop.org/forums/ubbthreads.php?ubb=showflat&Number=95245#Post95245

So expect eb Db/Db co+/co+ mo hens to be messy, considering they will have residual secondary patterning (Db/Db co+ doesn't give a clean black-tailed orange base with the hens). You could look through what Wieslaw has segregated in his e+ Db mo/mo L
