Ken, no, what I\'m saying is that some of those brown chicks will be carrying some of the necessary components to make the partridge color, but not all of the components. The e-locus gene is e^b, but then you have pattern gene (Pg) and mahogany (Mh) as well. All are inherited independently of each other. So instead of 25%, it is 25% X 25% X 25%. That comes out to less than 2 truly partridge chicks per 100 hatched. But since Mh and Pg are dominant genes, you will get more that show evidence of pencilling, but will be heterozygous; they won\'t breed true for those genes. Without looking it up, I don\'t remember if there are any more or not, so somebody can jump in here and help. But they all need to be homozygous (two copies, one from each parent) in order to get a good partridge color that consistently throws good partridge offspring.
