From a private Breeder. Its really hard to find private breeders near by you that sell these breed, So i'd start lookin' up some local breeders nearby you.. Most hatchery Langshans dont lay this pink color,
If you want pink eggs you must have Langshans! They lay amazing pink eggs every day and are very beautiful black birds. Heres a pic of some Langshan eggs
