Lovely birds! Sometimes it seems like mixes are the prettiest of all! Makes you wish they would just breed true to each other.... Umm, could you post some pictures of their combs? I'm not seeing anything really red. But, since they have Silkie in them, you might have to wait to be sure. Sometimes You might be certain on a gender, then later, it changes.(well, of course the gender doesn't change, but the appearance.)
