I am so sorry they are selling whatever that is as isbar/silverudd's blue. Another of the characteristic are dark brown to black eyes. Marans have the amber color eyes. Green eggs, and lots of them, are another consistent characteristic they need to have. They should also be medium sized, clean legged and good foragers. Mine have always been calm and non aggressive. They play well with other breeds too. My avatar is a 1st import silverudd's blue/isbar cockerel.This Is the black mottled SB cockerel. Got him directly from. GFF - but have been told by the general breeding community that the mottled gene is not desirable.
