Blue birchen Maran or Isbar?

I’m trying to figure out what this guys breed is? Thanks!

He looks like a mix. Just a barnyard mix.

But now that I look, he more look like an Isbar. Definitely not a Marans.

That is an Isbar. That name was incorrectly given to this breed - from what I've read- and it was renamed to Silverudd's Blue.
