Hello to anyone who is reading this thread! I have a question regarding black sex links (aka Blackstars)

So I've always seen people say that Blackstars and all black sex links are creating from crossing a barred rock hen to a RIR rooster or a New Hampshire rooster... However I'm pretty sure the real science behind it is that a solid color rooster (preferably red) has to be crossed to a barred hen because barred hens always produce barred sons and the solid color of father give the daughters some coloration in their black feathers which is why most Blackstar hens have red pigmentation around their neck feathers... but is this true?

I'm wondering because i have of flock of backyard mixes which I've been breeding for the last 3 generations and my most recent hatch ended up having a red cockerel and barred pullets... and I'm almost sure that if I cross them then they'd produce black sex linked chicks. These birds aren't ones I'm using egg production and are more so just for the fun of having around and experimenting with the breeding of! I know most people will go "even if they are sex links then they'll not be good layers" but I don't necessarily care since I have a separate laying flock i get my eggs from! These backyard mixes are also more of a "hardy flighty survival birds", and they all just hit 6 months!

You can see all 3 together right here:

I have a coop they do spend quite a bit of time in and I have another smaller coop I could move the trio to if i do breed them like I'm hoping to in the summer, but I'm wondering if they'd really create black sex links? They're only half sibling since they have the same dad but different moms with both barred pullets being related and the red cockerel having a different mother. the father had a crest too since he's part Cream Legbar.

This is the rooster more closely:

this was the father... who seems to have some kind of red barring? Barring genes are weird... 😵‍💫

Here are more photos of him! I think he only has one barring gene...

He was always incredible wary of people and was spending 90 % of his time deep in the woods and slept in trees rather than with other birds in the coop

This photo catches his feather patterning really well!

These were most of the hens he was crossed to

That’s incredibly interesting! I’m not very knowledgeable with genes but I did a little bit of research, and as far as I know, no one has tried experimenting to see if the real “code” behind black sex links is actually any solid colored rooster and a barred hens, but if you do breed Buttercup Jr. with the barred hens, I’m super interested in knowing what the outcome would be, and if the offspring would actually be black sex links!

And he and the hens are gorgeous by the way!!!
