That lady was incorrect. Any bird, even breeder stock, is liable to have an off-colored feather or two. Looks like one Splash (a color in which a few darker feathers here and there is actually completely normal) and one Blue, and they both look like Orps. It's a bit early to be 100% sure, especially with slow growers like Orps, but there's nothing screaming cockerel, so I'm gonna say you have 2 beautiful pullets at the moment.
