I figured as much; I'll cull her.
Any thoughts about the difference in the down colors, though? Why some are yellow and some more silvery-white? Would one be preferred over the other?
Speaking of melanizer genes; I did cull one female from a group of blacks that I had ordered at about 4-5 months because she had a "gypsy" face- the opposite problem--too much melanizing. Had I known, I could have probably kept her because she would have probably balanced the other issue. That was two years ago. I didn't take any pictures of her.
DMRippy, I'm guessing your little chick is going to have white tips on the wing primaries when she is an adult, based on what my splits have done when they have fully white primary feathers as chicks.
