Wow......well you can put up lattice and cover it in thick folliage either real or (cough) silk so that she can't view your property from her vantage point. I would make it a point to get some yard speakers and play strange music during the legal hours of the day.....maybe some animal tapes.....elephants.....exotic birds just get her used to the sounds which will also mask the chicken sounds. Some of my chickens squawk when laying eggs and some are silent. This way she may be less intent on spying on you. I live near a lion and tiger rescue place called Catty Shack ranch and early in the morning you can hear the lions roar. It was a little un settling the first time I heard them roar. After a while I got so used to hearing it that I hardly notice it anymore.
