Salt?

[JackieDuck2017]

Just curious we are currently giving our duck a lava stone, looks kinda like a pumice stone. She love love loves it. I was wondering about your thoughts on giving her a himalyian rock salt stone?

Just thinking maybe dehydration could be a possibility? I have never read anything about giving water fowl salt. Buy your duck a flock block instead.
