This Thread will be the Continuity of below thread, but will be dedicated just for this, to discuss the ideas on how to go about creating a bird with Blue grown color with black spangling..

so Blue does NOT Change black pigment to genes Melanotic(MI) or lacing in Extended Black background

here a few birds with melanotic Only, you cant see faint lacing but this is natural on blue birds

Now, I've seen someone go about trying to make a black laced blue, and, true Andalusians do indeed have a nice black lacing, so I'm curious if the following may work?

E^R/E^R, Co/Co, Ml/Ml, Bl/bl+


Or, and I'm sure it was mentioned, but sans the Pg/Pg -

E/E, Co/Co, Db/Db, Ml/Ml, Bl/bl+



All normal spangled birds don't have the Pattern gene, someone explain why it is needed?

OK, so now the question arises: what choice of breeds would one make to take the first step to an eventual blue spangled bird, and what would be the criterion for culling F1 birds? Say one has a well-marked SSH, what would be the breed of choice for hens for the first cross? What would be the breeding if you start with any Andalusian-source blue? It would be nice to be able to mix free-floating alleles, but since we're mere chicken-raisers and not working with Lex Luthor's laboratory, where do we start?

Quote:as stated above Blue can't affect Melanotic, Pg on Extended Black background so this will be the start,

if you could get your hand in birds with below pic quality that will be a great start
