Barred Rock Speckled Sussex Cross

[FromMysteryChickToLife]

I have a Barred Rock rooster right now, and I am getting Speckled Sussex hens soon. I will be breeding them. Do they breed a specific kind of chickens. If so, what kind? If not, what color will they be anyway? If you have bred these two breeds together, Could you upload a picture of their offspring? Thanks. Any advice will be appreciated.

What do you mean a specific kind of chicken? A chicken is a chicken.

The offspring should all be barred like their father. Half might be black if the father has only one copy of barring. All males will have red leakage.

I don't know, but you can find chicken genetics calculators online! I have fun with them. Of course it will be more fun if someone has some and can just upload pics. I didn't even know they had online genetics calculators until someone on here told me. I learn something new all the time!

Barred rock rooster over speckled Sussex hen will produce black barred F1s, if you are trying to create a very cool breed from those two breeds, I would say to breed back the F1s back to Speckled Sussex, once you get both barring and mottling on the same bird you will have achieved autosexing status as the males will look nearly white and the females will look like barred specked Sussex.

here is an example of both patterns into the same breed, the 55 Flowery Leghorns

Thank you so much!

Are 55 Flowery Leghorns the same as 55 Flowery Hens?

Yes, the number 55 is to point out that they were ready in 1955(breeding took place years before ofcourse) and they were bred from old strains of Leghorn by Martin Silverudd, a catholic monk from Sweden.

@nicalandia

Would you mind explaining what is at play here to be able to have a an autosexing "breed" that produces nearly white males and barred & speckled females... I'm trying to understand it but it's not "clicking" for me... I'm not seeing where the nearly white males are coming from.

thanks!

It's the compounding effect of sex-linked barring and autosomal recessive mottling on male birds, males have two copies of sex-linked barring(B/B) where the females only one one copy(B/-) due to the fact they only have one Z chromosome(Males ZZ, Females ZW)

Thanks for the reply... I have an understanding of sex linked barring and how that works... it's the white male that is I'm misunderstanding.

So let's back up, my understanding from your previous post was that the 55 flowery birds use a female and male like those shown in the picture in post 4 of this thread, to produce chicks that also look like the female and the male shown in the picture in post 4.

Maybe this is untrue and I was just misunderstanding what you were saying. But if this is true, then I don't understand the genetics behind that. In your last post, are you saying the barring and mottling combined produce a white male?
