I can't believe I am going to ever say this about OEGBs...But are self blue the rarest variety out there? I have a small flock given to me by a local breeder who had the gene crop up with his black and I would LOVE to find some more SQ hen line birds but that feels like to be nearly impossible! Can anyone help or will I have to cave and get some hen line SQ blacks to help with my self blue body types?
