Sapphire Splash is a lot closer in coloring and is also sold at TSC. I think that is far more likely. Mistakes happen. Especially at TSC.
Prarie Bluebell Eggers are supposed to have pea combs, so not that.

Do they typically come without them? Either way, no eggs (olive or otherwise) will be coming from this bird.
Assuming Hoover's uses CCLBs to create them after reading this. So I am assuming a mistake was made and a Sapphire Splash...
