Lavender and Buff Parents but black chicks?

[smcdermott]

Lavender Orpington Roo / (12) Buff Orpington Hen eggs, (3) barred rock Hen eggs

All babies basicly came out black??????? Just now, at 2 weeks old there are 2 that are showing some orange coloring on the back. Any ideas???

Lavender is a recessive gene that takes two copies to express. All the chicks are carrying a Lavender gene. If bred to another carrier or Lavender, you have a chance for lavender.

ETA: Lavender are basically black birds, with two lavender dilute genes.
