We have a 'collection' of wood pigeons nesting either in our trees or nearby. Up until now it's just been the amount of bird s**t that has been annoying but we've lived with it and invested in tarpaulin for the slide 
But now we have started growing our veg and the buggers are all over our patch particularly the radishes and peas constantly! I have a fleece membrane over the peas for now but am worried as they are getting bigger it'll start restricting growth and dug some last netting out for the radish. I've chased them off many a time and tried a water gun. 3 year old has also chased them
but they come back in 10 mins.
Do any of you wise people have any tips? Anything I can try? Something has been up rooting the shallots too but I think it may be the fox.
