Make sure you post pictures of your flock when you get them!
Do you know how the egg color is?
I'm guessing Bev means Blue Wheaten when she says "Blue tail Wheaten".
Splash Wheaten is also very pretty, imagine instead of a Black or Blue body a off white/pale gray body, sometimes with darker blue hues in the tail feathers. I'll see if I can find a image.
ETA: This is a Splash Wheaten Ameraucana, owned by peachick, a Splash Wheaten Marans would be colored similarly.
