By the way. My grandparents NEVER fretted this much about their backyard chickens. I bet people in Peru are low stress chicken keepers.Ivermectin 1% comes in an eye dropper where i live and the dosage is measure in drops. You are trying to say 0.05 mL where most people dont have a ml measure for 0.05. It is certainly posted on labels how many drops to give and comes in a bottle similar to medical eye drops.
There was an ivermectin paste question the other day that had a 5% concentration.
I dont use it much, but it is very heavily overdosed by people trying to use mL. The dosage of 1 drop evem works becaise of how the drug spreads in the metabolism.
