I've raised about 20 peafowl. They are wonderful birds; beautiful to look at, easy to care for, a joy to have. Even though I built an elaborate "Pea Palace" for them, they preferred to roost on the roof of our house. This was in Upper Bucks County, PA. That area of the country surprisingly has many feral peafowl, which could lure yours away. That is one issue. If I did it again, I would raise them with chickens, which do not wander too far and go into the coop at night. You need that tether, as with guineas. Someone to come home to/with, so to speak. They are great guard birds (not as good as guineas or geese) and will watch over your property carefully. They are LOUD, if that is a problem. I LOVE the noise, but close neighbors, close meaning < mile) might not.
Now that I have chickens, next on the list are the guineas, then possibly a couple of peafowl.
