I wasn't saying ask their permission. I was saying meet them and feel them out. So many folks are afraid to go talk to their neighbors about anything. Used to be when you moved to a new place, meeting the neighbors was a little ritual. Now, folks move and six months later they're on here posting about how they need to go out of town but don't know anyone local to watch their birds. Not cause everyone they know refused, but because they haven't met anyone local. I just don't get that. At least introduce yourself to your neighbors, and I like to exchange phone numbers so they can reach me in case there's an emergency. When you have animals, you just never know when one may get out or there's something else at your place that needs attention. My neighbors The Pot Growers have called us when our dogs got out and I was grateful. Pretty much all the interaction we have with them besides a friendly wave when we're both out working.
I agree that 175 feet is far enough away there should be no issue. Fences and landscaping can always be utilized to block line of sight, dampen sound and potential odors, etc. I also fervently believe if you're legal to have specific livestock on your property, neighbors should not be able to prevent that. But it's still a good idea to at least meet your neighbors and assess them as future friends.
