What do I see ... A peacock high percentage spalding Bronze color. What do I need as a starting 'material'? 1 - a peahen IB Bronze that brings color. 2 - a peacock Pavo muticus who brings the 'green' blood. Five steps. First cross : Pavo muticus X IB Bronze ► all peachicks are 50% Spalding (50% green blood) Split Bronze (one gene Bronze).Those birds are spalding color 'green'. Second cross : Cross sisters and brothers ► all are splading 50% color Bronze. Third cross: Splading 50% Bronze X Pavo muticus ► all peachicks are spalding 75% (75% green blood) Split Bronze (one gene Bronze).Those birds are spalding color 'green'. .... like this one . Fifth cross: Cross sisters and brothers ► spalding 75% split Bronze x spalding 75% split Bronze ► Spalding Bronze 75% ( like the first picture). BINGO ! One ... two ... errors? In fact, it's simple ... but it takes time!
