I haven't used either of those but I have seen them recommended so I'd say they are both good. Just be careful not to over dose. when you get time how about some pics, as you can see by my sig Scovy's are my favorite ducks. And I hope the rest are okay too.Well tractor supply was out of the nutri drench so I got some durvet vitamins and electrolytes and sav-a-chick electrolytes and vitamins.. Are these okay? We also decided to bring a few of the smaller ducklings inside, just in case. Hopefully everyone else is okay!
