I hatched this black opper Marans from a breeder

[MotherFlockers]

I hatched this BCM from a breeder that said they were bred to SOP. It has a brown patch on it's face I'm not sure of that is a flaw or if it's just something that will go away as it grows? Have any BCM breeders seen this before? It's the first time I've encountered this.
