I don't think I could ever trust her with the chickens. I've never seen a dog like her, she has a crazy switch and once it's flipped it's nearly impossible to turn her off. I believe she was bred from fighting stock and she just has a TON of gameness. Ironically, she's not the least bit dog or human aggressive, super friendly to every dog/person she's ever met. My old dobie gets really nasty with her sometimes and she never retaliates. But boy when she gets focused on something I believe you could harpoon her and she honestly wouldn't even notice. Seriously obsessive behavior, it's weird. I plan to really buckle down and work with her, she really is very smart, but very hard to keep her attention. She's just now around a year old so I'm hoping she'll start to mellow soon-ish and she really does need some more consistent work. I've been lazy with her training because my other 2 dogs are so good and she will just hang with them 98% of the time and stay out of trouble. But if something catches her eye, she is blind and def to everything else on earth.
