Its possible but no idea how for me creating lavender was a pain and isabel is barred right? I mean I probably could of when i had barred wyandottes but you would need lavender and barred. But first gen would be all split to lavender so wouldnt show until 2nd gen.
Scratch that is it laced? If so id use a lavender and a gold laced but if all would be solid black not sure how the lacings would be
To me, that looks like a lavender silver laced, not a lavender gold laced which is what I would call isabel. If you cross a gold laced Wyandotte over a lavender Wyandotte or maybe an Orpington, well that’s the first step.
