Tattoo in Rabbits Ears

Hope someone can help with this we have just had in two lovely Giant bunnies Conti's Bertha we have noticed is the owner of tattoo's in her ears. Is there anyway I can trace where she originally came from and how old she is from the tattoo markings. Bless her she was born with an underdeveloped eye ball and has nerve damage to her left hind leg which I am going to get my vets opinion on what to do as she drags it round and gets it tangled in her good leg.

Charlotte came to see them today and she agrees with me on how lovely they are. Well I had best get off and put them to bed as they are still ruleing the garden at the minute.

I am sure it is a British Rabbit Club thing. Someone will come on and tell us!
