I am doing a similar cross of 2 heterozygotes (both Olive Eggers in my breeding pen) and this last hatch of 22 chicks, only 2 were lavender. But I only need 1 cockerel to survive for the next cross in my project. I will hatch a few dozen every 2 weeks until I get enough lavenders to assure I can make a good pen.Great thanks. BTW: this morning had my 15th hatchling from Adam -- and it's a lavender! That's running odds of 2 out of 15.
