What is this pattern?

[wolfdale]

What colour/pattern is this hen cross on the back? And what breeds might be having it?

 

[Lady of McCamley]

It's a diluted red (orange) based bird with white secondary markings, bleed through.

Most Red Sex Links look like that.

To my (somewhat limited genetic knowledge) it isn't a particular color pattern. She isn't laced or stippled or penciled or mottled by what I would call any of those. It hints a bit of white lacing, but isn't.

My 2 cents
