Thank you Julie! So would it be a male Crele x female BO?

That would be the best cross. The barred male would give all barred offspring. If you switched with a crele hen, you'd only get barred cockerels and solid pullets.

Crele is Black Breasted Red crossed with Barred.

Why is it that it works that way? That a barred male gives all barred offspring but a barred hen only gives barred cockerels?

Because barring is sex linked. A male who is pure for barring, meaning he has two genes for barring, gives one to each of his offspring, regardless of gender. A hen who is pure for barring only has one barring gene. This is how you can sex barred/cuckoo birds by color. The two genes give the males wider white bars, making the bird look much lighter overall. A hen, having only one barring gene, only passes it onto her male offspring, not her female. that's the entire basis behind black sex links. Here's the classic thread with some good info...

go down to the black sex link part, he explains things better than I do.
