I'm almost ready to give my birds their second wormer after wazine 17 a while ago and I have safe guard liquid goat dewormer to use, 10%. What is a good dosage, I assume in water, and how long do I leave it out for? In a little research I found a dosage of 2 1/4 to 3 ml/gallon for 3 days. Is that reasonable? And is this safe for ducks? Thanks for any advice you may have.
