I was given an un-neutered blue dwarf rabbit a few months ago. I think he'd make an excellent breeding partner if you have an un-neutered female. I don't believe he has any genetic defects but unfortunately I have NO vaccination papers for him.
Alternatively I am considering having him neutered later on and he could do with some company (rabbits actually get lonely) so if you have an neutered male or female looking for company we maybe able to come to arrangement.
PM me.
