None of the Lav splits hatched? Isn't hatching so frustrating? I hate to hear that. I hatched one split last night and have 2 more to hatch. They are a Splash breeding though, so they will be harder to work with. But, the chicks are born blue, so I guess they'll be Blue Split to Lav.
Your whites kind of look the color of the whites I just hatched. I thought maybe they were split to Lav, but maybe not. Does have brownish tone? I can't even describe the color of mine. I guess, I'll see what color they are when they get a little older.
kaceek here's a list of breeders that I know have them. Of course myself, Sonew, AHappyChick and Oldtimeagator. The only one I have laying right now is my Buff/Lav split Showgirl Pullet. I have a few of her eggs in the bator to check fertility. My other girls are broody and one is too young to lay yet.
My Lavender birds are from Brens Birds of Paradise and Fawkes Feather Farms. AHappyChick also has some birds from Bren. Not sure where the other breeders stock came from.
