Hi,

I have just put a deposit down an a lovely little black rabbit with a star of white on its head from a local lady who's rabbits had an 'accidental litter', however, I am unsure of the breed (or mix of breed) of my new rabbit so that I can do research etc?

Any help or suggestions would be great! Thanks

I have attached 2 pictures of the rabbit and its siblings.
