I live in the beautiful wet tropics of North Queensland Australia. Our native fauna include; goannas, snakes(big ones), eagles/hawks and CHICKENS! The only animal I'm annoyed with however is those bloody Turtle Doves! They were pretty cool at first, there was a male and a female that would come every morning and take a small nibble out of the feeder and be on their way. Now however there's eleven. I have to de-lice my chickens 1-2 times a month. I'm spending a fortune on food and they keep lowering the water level in the waterer dangerously low. Any ideas on how to scare them? Should I make a scarecrow? I tried putting a fake owl up but that just made me feel like an idiot. Suggestions?
