Would this be the case with other breeds that were being bred to the Lav.?Not totally positive about this, but here's my input. Anybody free to correct me.
1) White Orpington offspring, split to Lavender. So they will look like Whites, but carry the Lavender gene.
2)Patridge Orpington offspring, split to Lavender. They will look like Patridge, but carry the Lavender gene.
3) Black Orpington offspring, split to Lavender. They will be Black, but carry the Lavender gene.
However, if you breed the chicks of any of these crosses back to Lavender, you will have a percentage of Lavender Orpington offspring. I think 50%.
