Oh I can't wait to watch those chicks grow up! They are lovely. All the self blue I've hatched have had racing stripes. But I'm really loving yours. I can just imagine the excitement watching those hatch from a partridge pairing. My porcelain cockerel (silkie from Sheri Minkher eggs) isn't showing interest in the ladies but I can hardly wait until he does. I only have 2 porcelain hens but I also have a partridge and lavender for him. Right now I have another batch of sheri eggs in the incubator (16 made it to lockdown) and Im really hoping for porcelain and partridge. I wish I had some answers for your mysterious BRIR chick. Could it be a really diluted splash?I hatched a test batch of eggs from a full brother sister Partridge match. They are both out of a recessive white female and my Catdance bred Paint father. . Two out of five chicks were self blue cream in color. In the test pen I also had a couple Bantam Rhode Island Red hens. The resulting chick was not what I expected. T This chick is a barney (half silkie half BRIR.) It's wing feathers are coming in self blue. Even the shaft of the feather! My feeling is that my Catdance Paint is passing the lavender gene. The full brother to sister mating of the partridge progeny of my Paint paired up and brought it out. But how did the lavender gene pass to the BRIR?
