At what age can I put ducklings in the tub to swim a little? I’m nervous as the last time we had ducks my husband had them outside for a bit of sun and gave them a little tub to swim in and we lost all of them within an hour. I was crushed and haven’t owned ducks since and that’s been a few years ago. But if we let them swim in the house for a few then back under their lights will they be ok?
