YES!  duh!  LOL  she must be Blue.  
  In which case, I won't be getting any black.  That chick yesterday must have been a VERY dark blue, because it was solid black!  
Hu?!?  LOL  Yeah, I read this a couple of times...  It doesn't sound like you have a rooster that is a solid color?  Not sure how they got white feet.  If your hen is black, you need a rooster that is a solid blue, black or a Splash.  I wouldn't use white to get to blue. I also would not use any rooster that has red earlobes.  
 
ETA-- okay, now I re-read and see your hen is WHITE.  I was totally thrown by all the blue rooster talk.  A white and a blue doesn't mean Blue.  I suppose it's a shot in the dark and who knows what odds there are to it, since you don't know the white background...*maybe* you could get blue???  I guess try and see.
