Hi Enola, I'm Ronnie...Aussies are awesome. I am currently looking for one as well. There are a couple of Aussie rescue sites you may want to visit but your not likely to find a puppy there. Usually they have adult dogs that are rescued from pounds or neglectful or abusive situations. Some are even "turned in" from their owners - Aussies are not for everyone - but they should be. Any way here are the sites I've been working with.
New Spirit 4 Aussie Rescue
Carolina Hearts Aussie Rescue.
Also Pet finder.com will link you to other locations that have Aussies.
I'm new to the wold of chickens, just got my first two last weekend.. Two Bantams and I want more. I love 'em.. My girlfriend, who was border line vegan say's, now, I know I can't eat any more chicken..... Personally, I still find them tasty...
Best of luck,
Ronnie
