Hi there, a mate recently got access to a pond and we are looking to release some mallard onto it. We made enquiries and we can buy some that were hatched this year but are now flying. Is it a waste of time releasing these on a pond at this stage (i.e. will they fly off never to return) or will they stay? If there is a risk of them flying off, would it be worthwhile clipping their wings to keep them around to establish some numbers. Suggestions welcome!
