I live in the UK, so we dont have a huge selection of aerial predators but I do have buzzards, though few and far between and my new coop and run, roughly 5m sqaured is covered by a huge tree. However I will no doubt get the attention of local crows, we have jackdaws and grey crow, thankfully no rooks which are very smart birds. I know they will likely want the food but quail arent so big and Im guessing will be easy pickings, can I rely that theyll run or what deterants can I put up? Does the old cd really work for long? I have the food left in the house, so they will have to risk going inside and may be cautious. Any other tips greatly welcomed Edit: They are in a 110cm high electric netting, which definitely gives off a bang!
