I have only had ducks myself that live to around the 8- 9 year mark- But I was surprised when talking to a family who came to buy some new ducks recently. There youngest daughter is now 18- but when she was two years old- she was bought a pair of ducks. The drake is still alive but the duck only recently passed away. She was blind and had athritis- but for a 16 year old cross bred duck she sure had a good life. They were concerned about getting such young littles ones again but the old drake has taken to them and welcomed their company.
