Adding my 2 cents. I know people that have huskies and have had a heck of a time trying to train them to ignore their natural prey drive. They are great with basic obedience like sitting and such, but trying to call it off the chase of a small animal is a battle. I know not all are like that, but I believe that is the exception and not the rule.
Now, to the two breeds I have had around chickens, rabbits and horses. A Pembroke Welsh Corgi and German Sheperd. The corgi loved to herd when it was younger and had a hard time sitting still and staying put while I was interacting with the other animals. It took about a year before she would just chill and not lend her herding skills unless asked to do so. The problem with Corgi's is they are too darn smart. Trying to stay one step ahead of her was tough, and they are mischievous. Which can be entertaining.....and annoying. They are great.....but require a strong owner who is going to take the time to train them and give them constant mental stimulation to keep them out of trouble.
Next, GSD. Since I got my first one two years ago I have decided that I will never be without one. By far the best match for my little urban farm. They are crazy smart, loyal and athletic.....but they are willing to defer to your better judgment and ignore their own instincts when asked to do so. This is one of the few breeds that have that capability. All I needed to do was claim the chickens as mine and correct her once when she started to chase one and she backed off them. Now she will follow a few of her favorites around trying to get them to play with her. She will lick them and let them walk all over her when she is lying down. Same thing with my rabbits. I know that she still wants to have a taste, but she respects my authority and overcomes her urges to make better decisions. That is what I love about them. She was rescued from the pound at the age of one as well, so it is not even necessary to start from a puppy (though I would, who doesn't love a puppy!). GSD still need allot of mental stimulation and exercise, but an active person willing to spend a few minutes a day on new training will easily meet their needs.
Good luck!
