Even 2 SOP parents will produce non SOP offspring on occasion. That could be the case here as they may have looked like SOP birds when she sold to you or maybe she gave you culls. Either way, they are Easter Eggers if they are Ameraucanas off their breed SOP. You should probably just contact the breeder and tell her what happened and ask for replacement birds that are SOP. A pairing of a black roo to blue hen should produce all black or all blue but no splash Accepted SOP colors for Ameraucanas are Black, Blue, Blue Wheaten, Brown Red, Sliver, Wheaten and White, so that bleed through is not SOP.
