It could be the way they look in the pictures or there could be genes that
you didn't think they carry, if they came from Kelly's stock within the past
few years it is possible they do carry ef since I bought some gerbils from
her out of stock I sold her many years ago and I am now getting silver
schimmels from an IC female that wasn't supposed to have any ef. So many
people have bred various colors of gerbils together it is nearly impossible
to be sure of what they actually carry unless we test breed them.
