What does poulardize meant? I know what caponizing is.
If you want black sexlinked chicks, you'll need a non barred rooster and barred hens. Otherwise, if you use a barred rooster, the barring can pass to both male and female chicks. There will be no 'sexlink'. The reason black sexlinks work is because a barred hen can only pass her barring on to her male offspring. It helps if you use a rooster that had dark enough chick down. It can be hard to see the white dot on the back of the male chicks heads otherwise.I've been doing this for years. My goals keep changing, thankfully that allows me to get more chickens!
I started out wanting high production colored egg layers. I bred brown Leghorns and Easter eggers and got just what I wanted--hens that laid a lot of large blue or green eggs.
Then I got intrigued by sex link genetics and decided I wanted a colored egg laying sex link. I decided the black sex links were easier for my purposes, so I put those hens under a sex link rooster and got all sorts of pretty barred hens of various colors. Some laid green eggs, some brown. I put the green egg layers under an Ameraucana rooster for sex linked colored egg layers. I also put some of them under my part Welsummer rooster for darker Olive type eggs. I also put the brown egg laying hens under the part Wellie for darker brown laying sex linked pullets.
I'm now looking for a nicer meat carcass, so I have a small breeding pen of Dark Cornish. My plan is to interbreed them with whatever dual purpose layers I have going next year and see how that does for carcass size. Only thing is, the Cornish aren't great layers and I don't want to really drop egg production.
