I am currently breeding several varieties of Red and Black sex-links and would like to start a blue sex-link pen. What are the best combinations? I can get a blue andalusian rooster locally, I have also found a couple of blue cochin roosters. Can any of these be bred with a barred hen to produce blue sex links? Also, could they be bred with a light columbian hen to produce sex-links? I have read Tadkerson's sex-link information thoroughly, but he doesn't address blue as much as the black and red. Thanks for any help.
