Nice looking birds, but not as nice to my eye as the orginal.
Here is what I came up with:
Change E locus to E/e+ only on the lavender hen, then hit calculate crossing. I'd call those black patterned silver incomplete laced pullets.
I have been using that for over an hour now and that's about what I got. The only thing I cant figure out is that it doesn't allow a partially laced bird with any amount of E. I'm wondering if the black Wyandottes used for the lavender project were ebeb partridge brown.
Is that possible?
If I use the genetics you have there except put ebeb instead of EE on the pullet then I can get a partially laced bird from the calculator.
Do you have pics of the chicks at hatch?
