thanks for that1) you know one parent is lavender
2) they have the lavender/self-blue phenotype and breed like lavenders (100% if bred to another lavender, 50/50 if bred to a black split for lavender, 100% black if bred to a black who is not split for lavender)
3) expensive DNA testing.
i was asking this as i wanna try making a coronation sussex
and as far as i am aware the black gene dilutes to grey and the red gene dilutes to buff giving lavender plumage
so i was thinking of crossing a light sussex [black hackles] with a buff orp then i was gonna cross the off spring with another lightsussex then that off spring cross with a lavender orp
then the resulting off spring with again another light sussex
hopefully keeping the sussex hackles but also inserting the lavender gene into it
