This is really helpful! Thank you!If you want more lavenders, try using just the black sons and daughters of the lavender rooster. Skip the whites, because you can't see lavender if it's also turned white.
Crossing two birds that are carrying lavender should give about 1/4 lavender chicks, 1/2 chicks that are carrying lavender but don't show it, and 1/4 chicks that are pure for not-lavender.
You've also got about a 1/4 chance of having birds with a not-black base color. You could even get one that is then diluted by lavender (about 1/16 chance). Porcelain d'Uccle and Isabella Leghorn are examples of "lavender" chickens that are not based on solid black--the lavender gene affects both red shades and black shades.
