Not really the same since you have chickens involved, but I know two people close to me that kinda have to put up with this. My neighbors did this with the compost pit, putting it right up against our property line, and another has cars and rvs that their neighbor put on their property line blocking their view from their living room windows.
Personally if I were the coop owner and someone came calmly and spoke with me about it, I'd be willing to cooperate. Is probably ask for help moving it, (you knoe, physically moving it, catching the chickebs, collecting my bowls and stuff, that kinda thing) but if be much more likely to be willing if it was brought to my attention before I suddenly had tickets and notices sent to me
