Thats what I thought happens, I tend to do that frequently. I do appreciate people catching my mistakesI must've misread it. It happens.
Okay that's really interesting. Since the roos have two copies instead of just the one, it should be easier to pick them out from the hens.I think there are a few different auto-sexing colours I don’t know too much about them. They can be sexed at hatch be down colour like sex-linked chicks. Barred chickens can be auto-sexing if both parents are barred, the barred gene is incomplete dominant which means if a chicken has two BB they have wider barring then if the had one B. This causes the head spots on the chicks to be bigger if they are BB. But if they are not bred to be auto-sexing then it might not be a reliable way to sex them

And ID is sex linked as well, right?The ID/ID gene dilutes leg color. You can use this gene to turn green legs into pure yellow legs, or Slate legs into Pink/White legs.
Yes, it is. To take advantage of this is to breed a black skinned male to a white Skinned Females. You'll get female offspring with black skin, & males with white skin.And ID is sex linked as well, right?
So hens only have one copy?
It's Z, & W for birds.My understanding of the terms Auto-Sexing and Sex-Linked are as follows:
Auto-Sexing = When the sex of a day old chick (or 2-3 days old) can be determined by looking at the down color and patterns. For some traits - Male chicks and Female chicks have different down colors and patterns. I think the term is Sexually Dimorphic?
Sex-Linked = Refers to a particular genetic inheritance rule. A male bird has a chromosome pair X / X and a female bird has chromosome pair X / Y. A sex-linked trait will only be present on the X chromosome.
Some people use Sex-Linked traits as a tool for reliable sexing. If they breed a combination of hen and rooster which is known (using the sex-link rule above) to result in different colored hens and cockerels - this can also be reliably used to determine sex at a young age.,
