I bought Lavender Orp eggs from a breeder on BYC. Only one of them hatched gray, the others hatched yellow. The person labeled the shells "LO", and the eggs were light colored brown. Since I have absolutely no experience with this breed, can anyone why? Will these chicks be a light gray when they mature, or is it something else that I don't want to learn and will be unhappy with? Please help. Thanks!
