So my ducklings will be here on Wed and I am trying to figure out when and how much of the Nutri Drench I should give. If I did the calculations right it should be 1.5 tsp per 1 cup of drinking water, right? 4 oz per gallon is what the instructions said, but did I read it correctly? I know my math is right but is that how much you really do use? Also do I need to have normal drinking water as well? I got the grow gel with them. I'm sure I will be back with more questions. I also started to give some to my adult peakin because he gets kinda wheezy for no reason and will whistle every now and then. I tried Apple cider vinegar and the electrolytes and now this. He is fine and healthy otherwise and it has been going on for over a month now. My other does not sound like him, so I have no idea what it is.
