No.... not like that. I have seen some with head spots but that was when I had EE in there too. That looks blue but never seen that white back on ANY chicken... strange.
@howfunkyisurchicken I have never used GOLSN. I look there but never posted. If you need someone to help with SG eggs I have a pen of a Black SQ cock and 2 Blue SG hens. I am not hatching right now so all my silkie eggs are available. I have a fun Frizzle pen with a White Frizzle Cockerel and a Reg Gray Silkie (Silver Penciled) over 1 White SG 3 or 4 Silver Penciled Wyandotte bantams, 1 White Amerucana Bantam. I only hatched a few before I had to stop hatching. I have some paints and another Splash x Black SQ pen.
