These duck diapers and leashes come highly recommended from owners of indoor ducks on instagram! I’ve tried other diapers, but they do not give proper neck support.. It’s important that a duck diaper is very adjustable and provides a ring for the neck, else the straps will cut into their wings. It’s also a good idea to do some sock training with your duckling to get them ready for the adult diaper if you are planning on keeping them indoors.
