Hello, I have been busy hatching away this summer with my single, 3 yr old BS male, 2 BS hens and 2 IB hens. I am surprised to find that I have 2 purples from these birds. I do not know what is behind them genetically as I bought and raised all but 2 as chicks. Wondering if both must be split to this recessive color or? I am assuming it has to be one of the IB hens since they are not BS purples.
