I'd like to keep an option for showing open.I have no Pearl Grays. i have one Lavender hen, Coral Blues, Sky Blues, Chocolates and one Royal Purple.
I regularly produce Royal Purples and Chocolates from the pairing of a Chocolate cock and a Coral Blue hen. I used to have a Powder Blue cock. When he would mate with the Royal Purple hen, they would produce some Violets.
The only thing you need Pearl Grays for is to produce other Pearl Grays.
