I went and got some Nutri drench and I’m trying to just give some in the water but there waterer is small for chickens and to avoid wet bedding I put about a cup at a time in it … it gives 4oz for a gallon but there water is no where near that size so trying to figure out conversion …damn I knew I’d need math for something in my life 
And way trying to figure out how much to put in like a cup of water? All 8 chickens can have it …it won’t hurt them so?
