Sorry, but because all my goslings are going to be Christmas dinner, I didn't sex them. So breeding blue to gray saddleback, I got 3 nicely marked saddleback (1 light clear blue, one gray, and one buff) and 3 blue (2 normal blue and one dark charcoal). I have no idea whether the colors split along the gender lines, which would at least indicate that there is some sex linkage. Although 1 hatch certainly wouldn't prove it. 6 goslings split along the color lines could simply be by chance.
