I realease 5000 reared ducks and the best way i find to get they flying nearly as well as wild ducks is do not exceed feeding them more than 25kg of food to 500 ducks, and when they start flying in off the banks is to start feeding them off the ponds by calling them everytime you feed them either with the horn of the truck or using a whistle, afer a few weeks of training you could take them a mile away then get them flying back, just let them go on there own dont push them back otherwise you spook them. and remember little and often, if they dont come out to where you want them dont feed, just
