so I think she is a capped then. I bought these two off a guy who is breeding for feeders he only had a few rats, he said thats my big stud! it was white and grey and also a dumbo. when I told him he was a dumbo he had no idea what I was talking about, I'll message him to see if he was the father for sure. Also if they were het dumbo and she had a litter could I raise a boy and breed back to get dumbo?
