I dont have a blue but I do have a black. His eyes are marbled and not great but his copper is much better. How hard is it to work with bad eyes?
I have not worked with the marbled eyes. I would think if you breed him to a hen with correct eyes. You would get some with correct eye color. Chooks man or someone else with more knowledge will chime in I'm sure. I am so sorry you lost your rooster.
