Good Morning! I am a brand new member and a brand new duckling mom. My Flying Mallard ducklings will be three weeks old soon. I have been keeping them in a large dog crate, and anticipate moving them outside within two weeks. It has been chilly here in southern Pa. I have a brand new covered enclosure to place them in once the weather becomes more temperate. Meanwhile I have been letting them swim in a small sink and have noticed that they are oiling themselves well. I have been feeding them kale, non medicated crumbles and cottage cheese as a treat. My question for you all is this. Once my husband tills my garden I thought I would let my ducklings out for a worm forage. I read somewhere that I must worm my ducks twice yearly once they start eating worms and such. What do I use, where should I purchase it and at what age should I begin the worming process? I have found the sticky post on feeding ducks very valuable and commend the author! Thanks for the help!
