I used rain water, spring water and R/O filtered water for my ducklings, but with six of them at nine weeks, it's tap water.I have some ducks hatching soon and I would like to know if I can use tap and hose water for my ducks. While they’re small I would like to let them swim in the bath tub/sink. When they get older the plan is to get them a kiddie pool and fill it up with water. This is my first time hatching anything and i’ve researched for 3 months but never found out what water is safe for them.
I do supplement their iodine from time to time.
