I have a lot of other animals ......many of my goats are rescued goats. At the moment I have 12, of various breeds including pygmys, and two entire billy goats. Other animals include sheep, cows, llama, plenty of farm cats, dogs, rabbits, and lots of ex battery hens and bantams. Not cunted lately but I would say there could be 80 at any one time, rising to 200 plus when we do a rescue and have hens waiting to go to new homes. Plus 9 native ponies which we breed from.
As to the CAE test, your vet will be able to do your goats now. I personally do not have mine tested. As an established goat keeper of 35 years I am well aware of the risks, but have never had a goat showing signs of CAE. All my animals are kept in as near a natural environment as I can have them and none of my animals are ever injected if at all possible, or any tests done, or drugs given. My only exception is to have the horses injected for tetanus, and the mares being sent for stud are swabbed. Obviously, this is all because of my personal preference, and I do understand other goat owners having the CAE test.
