I know Sumatra breed tends to grow 4 spurs but not always. Wanted to know what anyone knows about the gene that makes it possible and what the likely hood of offspring to carry this trait. More interested in how the trait would carry over if you need a cock with four spurs who kept having cocks who almost always have four spurs then bred a hen of its offspring to another breed. What would the likely be that the mix would develop four spurs. Or would it be more likely to breed the pure Sumatra cock to another breed hen to get the four spurs trait and the need to back breed to further the four spurs gene. Genetics are fun and just thinking.
