Please excuse the fact that I'm not at all familiar with identifying chicks... but just looking at Hoover's website as to what bantams they sell, is there any chance it's a Mille Fleur d'Uccle?
No I have some of those and mine never had spots this really just the black wing tips. I would love another one though! I'm down to 1 older pair and 2 babies in this mix thanks to critter attacks oh and I got porcelain d'uccles! I highly recommend the crested polish mix and bantam mix I got so many different breeds!
