I have a line of mostly Araucana with layers of leghorn & cream legbar infused in. The cream legbar heritage has produced some novel patterns and colors over the years and whenever I see red patterning I try to bring it out but historically they were always male, I finally got a hen last year purely red/gold and this year I have a rooster with red on the back and a blue undercarriage and 2 pullets with similar coloring. I suppose brown leghorn crossed with blue would be the best way to describe it. I'm thinking of turning this into a breeding group and wondering how best to describe them. I've included some pictures so curious if anyone has seen a pre-existing colour/pattern that resembles this or if not what it should be called. The hen from last year has no blue at all in her and my camera seems to have a bit of a red shift that turns blue eggs white when photographing but you should get a rough idea from these pics.
