Do I want to learn about genetics? Yes. Is it very intimidating and scary? Yes.

Barring is a sex-linked dominant gene.

So all of these sex link breeds have barring in their genetics?
Either way, seems like Barred Rocks have a very important place in genetics. I mean they all do, but BR's just seem to be a large part. Maybe it's because that's where my genetics wonderings began

I was wondering about the crested gene because of this guy. He has a blue silkie father and a midnight majesty marans mother (MMM is a cross of Marans - my bird has clean legs and feet that are slate in color, she's solid black, and has a floppy straight comb). Is he an example of recessive genes (I was thinking BCM) or male specific genes (thinking BCM again) or he is what he is? I wasn't expecting him to have a crest, but I love crested birds. One last question and then I promise I'll stop. Is the floppy comb a gene or just something that happens with the larger combs?

Thanks again! I've been wondering these questions for so long

His mother likely has the genes for leakage, which is more obvious in roosters. So, if she was a rooster, she would have leakage, and thus was able to give her son those genes. The silkie father might’ve had some leakage too, since that’s common for silkies. This is due to the fact that it’s hard to tell if silkies have a bit of leakage because of their feather type.
As for the crest, I would expect that of a Silkie cross. Though not all silkie crosses have crests.
I’m not completely sure about the comb. Could be due to the crest. Legbar roosters often have floppy combs because of their crests.
Also, ask as many questions as you want! I love answering them, and I’m sure the others on here do too.

Not all sex-linked crosses use barring. Though many autosexing breeds have barring.

The cockerel I posted a picture of is the only bird that I've hatched from my own birds. I'm hoping to cross my Svart Hona with my Blue Silverudd's Blue (I don't know how that's supposed to be stated because I thought that all of the formally known as Isbars are now Silverudd's Blue, so his coloring would be stated first maybe. Idk. Please overlook this if it's wrong) to get Swedish Blues. I guess I need to start looking into those genetics. I'm wondering if they'll all look like Swedish Blues or if it's one of those instances where only a percentage of them will come out black with light leakage. Since I already promised to stop asking genetics questions, I can ask about this another day. This is all just so incredibly interesting

And if this happens with first generation or if it has to be a process (F1, F2, etc) . I didn't even consider that it might not be something that happens with the first generation until right now

A blue isbar x Swedish black should give you 50% blues and 50% blacks. You’d probably get some with leakage and some without. I believe they would have black skin, but all I know about black skin is from looking at various threads about silkie mixes.
@Amer can you confirm?

That depends on if you want a flock of them that are true breeding or just a few blue chickens with black skin to look at. I think you could get it in a first generation cross pretty easily.

One thing I want to learn about is the Dwarf gene. I have it in my silkies, not all of them. I have 2 Dwarf Silkies, that I hatched this year, & they're tiny.

I know of an article that talks about the dwarf gene, but I believe it’s the lethal type: https://www.backyardchickens.com/articles/thyrogenous-dwarfism-in-poultry.72684/.

I did hatch a Dwarf earlier this year, before the other two, & she died unexpectedly. Not sure if that had to do with it, or not. She was 7 weeks old, when she died.

I'll look at the link in a minute. Thanks.


Here's my previous Dwarf.
