Which rooster to keep for sex linked offspring.

[Vkamiko]

New to having roosters and even the possibility of hatching our own eggs.

I have 2 roosters. 1 i think is an Isa brown and the other is a Rhode Island Red.

Would any of these roosters produce sex linked offspring?

We bought 9 day old chicks to start our flock and 7 chicks were roosters and only 2 hens. The heart ache when our favourite hens started crowing...

Not including the 2 roosters we have the following hens
Frizzle
Australop
Leghorn
White rock
Isa brown

Any help would be appreciated.

RIR over the White Rock or (assuming it's white) Leghorn should produce red sex links

Thank you.

I don't think RIR over a white leghorn would make sex linked chicks. Where leghorns are typically dominant white over a black base. So all the chicks from this cross should be white with leakage regardless of gender. I'm not sure what kind of white Plymouth rocks usually are, but unless they are silver based i don't think that cross makes sex links either.

I know one way yo make sex links is a solid color rooster over a barred hen. Correct, @AinaWGSD ?

Yes, and RIR rooster over barred rock hen is a classic way of making black sex links.

But unless the frizzles are barred (less likely) op is looking to make red sex links. Which requires a gold(red) rooster over a silver hen. Silver is dominant and only carried on the male sex chromosome. It works the same way barring works for making sex links.

Females sex chromosomes are ZW, males are ZZ. Because the sex linked gene carried on the male (Z) chromosome is dominant a bird only needs one copy to display that trait. So if Z is silver or barred, birds that are ZZ, ZZ, or ZW will be silver or barred. So if a ZZ rooster is bred to a ZW hen you will hatch ZW female chicks and ZZ male chicks.
