It was Levi and Hollander, though, who worked out the inheritance of the mutation and allowed us to create the andalusian color whenever we wished. For anyone who wishes to add a touch of color to his flying loft, indigo is a fantastic modifier to work with. There are no drawbacks to it. By that, I mean, it s not like almond or dominant opal which shouldn t be mated to one another lest hatching suffer. Indigo to indigo matings merely produce ash-red mimics which can be mated to blacks to produce andalusians in quantity.
Indigo is also fairly common in race birds now.
It s by no means something you find at every shipping, but a little hunting should allow you to find one to cross into your stud. If you d like to create those prettier laced andalusians, I ve a little trick from one of the best show breeders in the world. Once you ve got your andalusian-colored pigeons, stop crossing them to black. Black, at least good colored black, has lots of yucky bronzes. These bronzes make the black shine like a crow, but they don t do much for andalusian, creating instead a muddy coloration to the shield.
