They are blue golden duckwings. I don't think anything was mixed in anytime recently to get those colors. I would just say it's just the results of many generations of hatchery breeding, and/or you just got unlucky. Although Ideal says they have blue reds, what they actually have is a pen of mixed all colors of "duckwing' plus blue in all versions, so you could get Blue Reds, BB reds, Splash pyles, Blue goldens, blue silvers, golden duckwing, silver duckwing, etc.. They are not great, but, I have seen a lot worse. If you have good Zook birds, then, no, I would not breed them. Just let them be yard art.
