Cecil:
If you want to borrow my 17 MachII, that'll take care of them without worrying about the well house. After handling one a few years ago I couldn't believe how thin and small the body was underneath all those feathers.
If the .17 might be too strong for you, I have a pretty accurate .177 pellet gun that will hit a 1" target @ 50 Yds consistently.
When I did have a permit (couldn't afford it this year) I preferred the 3 1/2 inch shell with # 4 buckshot. It did the job but I also had to replace several jugs that were used to float may cages.
I also used a .22 with CB rounds complete with a scope. The CB rounds are not very loud at all.
