I think that keeping your dog away from the chickens will only increase the dog's curiosity if she can see them out the window but not being able to get them. I would say the muzzle idea someone suggested might work, but I think you just have to keep her on the leash and take her every day to visit the chickens so your dog can get used to being around their presence. Soon enough it will feel normal to have chickens around and her curious instinct to chase and bite, will hopefully cease.
I'm no dog expert, though I do have a dog myself...... with mine, sometimes her instinct will 'kick in' and if the chickens starts running she will kinda chase them. For the most part she doesn't have much interest in the chickens but I do get the 'instinct' part where people talk about it, it's like a switch that turns on which have been pre-programmed in them, but as the owner you have to know how to keep that switch in the OFF position best you can.
