SafeGuard Liquid Goat Wormer is given orally for 5 consecutive days at a dosage of 0.23 ml per pound, which is about 1.25 ml orally for a 5 pound hen. It has to be shaken well before drawing up each dose, and it settles out in water, so it is not accurate to give it in the water. If a hen is not drinking well, you would not know if she has taken enough of the medication.So if I wanted to treat 4 hens approx 5 lbs (silver laced and blue laced red Wyandottes), what would be the calculation for 2 qts of water? I'm great at math but didn't do well with chemistry and conversions, lol.
