I usually don't like naked necks but your silkies with the dark skin showing are actually pretty cute. For some reason chickens with a red naked neck look rather scary to me. My son and his girlfriend recently got pet chicken chick's a few weeks ago. They only have 6 chickens they have 2 silkies, 1 houdan, 1 polish and 2 lavender orpingtons. I don't think they plan on breeding chickens at all. They wanted a small flock as pets for the children and they're not big egg esters, so just a few eggs are fine. The chickens are a few weeks old now and are all very sweet little creatures. They really love their chicken treats. I enjoyed watching your video, you have some beautiful chickens. It was interesting to see adult versions of some of the chickens my son has.
Looks like a good foundation of breeders there, but just to offer a pointer from experience I would run a blue rooster over the blue and splash hens as running splash over splash can wash them out eventually with time.
