Culls for John, yes, but for me, well...the only thing I don't like about the white is he carries his tail down. Not sure if he was injured or just terrified.
But, that being said, is the black split to lavender to have that coloring possibly? And has anyone else seen a lavender go white? John would not have known that is what it was going to do because he sold them as young (week old?) chicks.
My lavenders carried recessive white. When the chicks hatch you can see both lavender and white on them. the more white showing in the chick the more likely the chick will be white when feathered.
I am no longer using those birds. I have new one for this year from Paul Smith.... we will see what I get this year.
