If you have room to introduce some less colorful stock, you will see the color shift before long.
Done! Next spring, I have a new up and comer, Eli, that I acquired from duluthralphie. He's very cream, and he's a C line whereas I have A/B lines, so he will bring in a much needed infusion.
It's not the most flattering picture I know, but he is handsome and I have high hopes that ralphie's lovely saturated blue eggs come into my line too, as though I have blue, I have green tinted too.
