Turks are often too curious and social for their own good. They need fencing. Granted, a few will take flight (six foot is pretty effective), but most will stay put.
If not the neighbor, some pred with no such polite scruples (they did let you know) will appear to tear up your investment.
Just a cautionary tale from this neck of the woods (about eleven miles North as the crow flies):
The farm where the Ryland house sits was a crime scene in the early 20th century.
According to accounts in the weekly Higbee News, 53-year-old William Ryland on July 30, 1917, sent a servant to call on next-door neighbor William Roberts to ask him to keep his turkeys out of the Ryland yard because the turkeys were eating corn Ryland put out for his hogs.
Roberts did not appreciate the suggestion and ran to Rylands farm.
But Ryland ran him off with a breast yoke, as the neighbor uttered a "vile epithet," the Higbee paper reported.
Roberts went home, grabbed a double-barreled shotgun and went back to settle the score. Ryland, who was holding an ax, thought his neighbor was bluffing as Roberts approached with the gun raised.
"Roberts fired both barrels, filling Rylands body from his knees to his neck full of shot, said to be No.4s, and killing him instantly," the newspaper reported. "Following the shooting, he surrendered to the officers."
