I just bought Nutri Drench & the measurements are confusing, my ducklings are 3 days old, i'm not mixing it by the gallon i'm just mixing it into their water container it holds 1 & half bottles of water which is about 24 oz , the dropper that comes with the nutri drench is in ml, I tried to do the math & came up with giving them about a tablespoon, is that correct??????? I don't want to overdose them.
