That helps. I’m struggling a bit to tell whether that hen is wild type with mottling or Millie Fleur, but wild type often has darker wings. Base on Millie Fleur is usually eb, but you’d have to look at down color to tell.
e+ and eb look similar, but e+ is very clean-cut, with one defined eye stripe per eye, and head stripe. eb can have hectic eye striping, a darker head, or other forms it presents in. I don’t have any photos for example at the moment.
If your hens had dominant white, they wouldn’t have a single black marking- but still the gold coloration. From the video, the hen certainly has black. By base, do you mean under fluff? Or just color?They’re overmottled, I believe. Mottling has a lot of variation in how it shows. If you want less white, keep back the growouts with the least mottling, and select toward less of it. The rooster doesn’t have much, so having him to help breed away from overmottling is good. The calculator doesn’t ever help with the nuances of color, just a baseplate for what the color may or should look like, ideally.
