Blanca Duck (White Layer) is one of my oldest ducks, over five years old and she frequently breaks the sound-barrier for food. No problems with feet, legs or hip at all - except when she became hypothermic this winter, but that was neurological. - I am sure she is no longer laying, as she sometimes grows a drake-like feather.lol why why. my white layers are very similar. They are walking slower and sometimes need rest in ducky hospital room too. they are 8 years old and weight almost as much as Chubbs. not very different imo. they also have laying issues as they are. i think because they are bred to lay so much, they have issues in older age.
