I think it is a good idea to have the in depth talk with the neighbor to get a better understanding of what you will need to do to keep everyone happy. Maybe a more distant crow is all it will take. Good luck and update as needed.
I somewhat disagree. Assuming other codes (setbacks and such) are being followed, an additional half acre would make no difference. This appears to be another case of "I want a more country life without hearing the country".
