Now if someone coulkd just write up the squares for tufts for Araucanas... and one for the BBS I would do it but I have NO idea what letters/combinations to use
The tuft gene is a whole new ballgame. Two copies and it is fatal (chick dies). Even in many cases a single copy of the gene is fatal. Read more here..
I used BB to represent a splash bird (2 copies of blue gene), Bb represents a blue (1 copy of blue gene), and bb represents a black bird (no blue gene).
