Is this safe for peachicks?

[Waterfaery]

I have bought a vitamin / electrolyte / probiotic supplement to give to my chickens follow a worming treatment. If it helps, I'd like to give it to my peahens + 3 week old chicks as well. Is there any reason why it wouldn't be safe? Here is a photograph of the ingredients.

Giving a probiotic after giving antibiotics is always a good idea. De-wormers are not antibiotics but it still can't hurt. If it is hot there the electrolytes are a good idea.

Remember when you are mixing a batch to throw out previous water and start fresh. Otherwise the concentration increases with each addition.
