Hello Mama2six, I am not an expert, but your dam looks Heterozygous ED Black to me.
Here is the link I found this info:
Chocolate Syrian (the first pic on the right top looks similar to your dam).
She allso looks a little bit like hamster in the second photo on the right column. That one is chocolate. So you probably know the ancestors, so sorry for bothering
I am also interested in chocolate hamsters. I have read that in Europe they are chocolates, and ED is more common in US.
