nekomi - what a GORGEOUS DOG!!! Amazing. You are so lucky.
Littlelemon-
I think what everybody is saying about how it totally depends on the dog, is true. However, it's not true that it takes lots of training if the dog has the herding instinct. My grandfather had (he passed away, now his wife has her and she still does this) a border collie who herded his chickens and guineas everyday, all day, whether anyone wanted her to or not. She never so much as displaced a feather on one... just herded them around. No one taught her - she just did it. She had no training at all. And if the chickens were put away in their run, she'd find something else to herd - kids, other dogs... even skunks! Trust me, that one got old... the ckunk would spray and spray and she would just keep herding it into one place so it couldn't leave... she didn't care about the spray! Anyway, the instinct is strong in some dogs. But, even some herding dogs and be nippy when herding, so it depends on the dog. The other thing to consider, as previously mentioned, is that huskies have very high prey drives and are the total opposite of herding dogs... most would only think "food!" when they see chickens, no matter how much you try to desensitize them. There are always exceptions, but that would be the standard instinct of that breed.
So, I guess the summary is - who knows how your dog will be! It will be interesting to see, most certainly. But, be careful around the chickens until you know for sure. Good luck!
