And there are hunters in the American culture who hang their deer for a few days, depending on the temperature.
The best thing to do is to have someone translate a letter written from you to your neighbors and you give it to them. In the letter, just politely ask that for the time being, please don't display any carcasses and tell them that you are trying to sell your home. Or you could go to them with a translator. Invite them for coffee or anything else that will set a nice tone to the visit.
Other than that, you could put up a privacy fence. But that entails a good bit of funds.
Back to the "positive" feedback. Have you received any complaints from the prospective buyers about the "view"? If not, the only concern I would see is the listing price of the home, don't you think? Speak to your agent about the concerns, unless you're selling on your own. In which case you should contact a real estate professional.
Hope that helps.
