My only means of Japanese Beetle control has been hand picking them off the plants everynight. They seem to really like my Raspberry plants.
DH and I don't like clipping their wings either but we've lost 2 chickens in the last couple months getting hit by cars and last fall Rosie followed DH up in the woods during deer season. He carried her down out of the woods and at Christmas 3 of the jakes went across the road into the woods there. DH, again went after them and he fell down the hill into the road. Although we feel bad about doing it it's the only way we can have them.
BTW, I have pictures somewhere of Rosie on top of our house roof. The other turkeys would walk around on the ground following her walking around looking up at her. Very funny.
