Thank you everyone for your replies!
I have actually now brought a billy who was for sale very close by because my nanny wasn't tested for CAE and apparently it takes a long time for the test results to come back and I was worried that the breeding season would be over at that point. I will get her tested sometime anyway. He is in with my nanny now and he does smell, but I don't really mind it, it is not as bad as the pigs!!
Bramble&Rose Dairy, I was actually considering buying an Angora billy, since they are gorgeous! Thank you for your kind offer anyway!
