They are really well bred. In all honesty- I would go back to the person you got them from. If that is the original breeder, then they may well have had enquiries from people looking for their stock when they haven't any more to spare. From a breeders point of view, there is nothing more heartbreaking than selling a really good animal, to someone who later decides they can't manage, and then advertises the goats anywhere. Had it happen to a friend, who let some nice goats go, and a fortnight later they were advertised on the notice board in the local tesco.
Even if the breeder can't take them back, they will more likely know of someone looking for that quality of animal.
Good luck!
