If it took the neighbor almost 2 months to mention to you that the noise was a problem, and you are in an area with an Ag. zoning, I think you're pretty safe. Ag. zoning is a pretty solid thing, especially in rural/semi-rural towns in Northern New England. If you were in a strictly res. zoning, you'd be SOL. I think that your neighbor has, at best, an up hill battle. He might try and fight to change the zoning in your neighborhood, but that's your worst case scenario. At best, the zoning board would look at your neighbor and tell him that if he doesn't like the noise, he should sell his house and move to the city, because he chose to live in an ag. zone and should have realized that there might be animals making noise in the middle of the day.
A 1 acre lot is plenty of space for a dozen birds, and a couple of goats. There shouldn't be any issue with animal manure, if taken care of appropriately (deep litter method, composting, etc.)
Where I'm at, there are 5 types of residential zoning in the town. only one of them explicitly allows the land to be used for traditional purposes (agriculture/logging/etc.) there are 2 others that imply these uses. Additionally, a good portion of the town isn't zoned at all, which, by default, allows agriculturaly practices. These practices include livestock. I'm not at all sure what other neighboring towns have for their zoning designations, but would probably be somewhat similar. For my intents, where I am at right now, I cannot have "livestock" being on a lot of 1/4 acre, I can understand, to an extent. What I want is a large lot (10 to 20 acres), that is either not zoned at all, or it is zoned as explicitly allowing traditional practices. Some of these lots are on my current way to work, which would shorten my commute, but increase my wife's. Others are further out, increasing both commutes. I'm okay with either. My wife would take some more convincing. I've been working on it for 7 years, I figure that I still have at least a couple more to go to convince her.
Didn't mean to hijack, just wanted to post a similar perspective.
