I think if you have a huge field you just figure that the birds are going to take a percentage. Of course, turkeys were non existent back in the 1970s.
I remember going to large PYO fields in WNY state south of Buffalo. They had the guns that would go off every 15 minutes to keep the birds away. They also had fake owls around the field. Turkeys are great for eating ticks and grubs. However, when you have a flock of nine birds hanging around 24/7, they could eat all the blueberries off of my seven bushes in a day.
I just bought netting on Amazon.
We have flocks of turkeys wander through our yard on occasion.
I wish they’d eat more ticks.
