That's interesting, and I imagine those would be great layers. madornato, I wanted to add something to what I said earlier. I told you that you can use any non barred roo ( that's not Dominant white like Krys said), on a Barred hen to get the Black Sexlinks. That is from a non barred on a barred cross. The possible roo colors useed could be: RIR, NHR, Buff, Black, Blue, some Whites and basicly any other non barred roo. BTW, if you use a Blue or Spash roo on Barred hens, you will get solid blue hens and blue barred males. However when creating the Red Sexlinks with a hen with the silver genes, the roo used must have gold genes, ex: RIR, NHR, Buff, Partridge, etc... You can not use Black, Blue, White, etc... roos, because they don't have the gold gene. Just wanted to mack sure you under stood that.
