I'm using safeguard for goats to worm my chickens. The vet gave me this example: dosage for Safeguard is 20 mg/kg. The math is straightforward to figure out how much you need to treat your birds. To convert pounds to kilograms, divide by 2.2. So if you have a 4 lb bird, divide 4 by 2.2 to get 1.8. To figure out how many milligrams you need, multiply by 20. 1.8 X 20 = 36. So, you would need 36 milligrams to treat one bird. You’ll have to look at your Safeguard to see the dosage of the solution to determine how much you’ll give each bird. This is still mind numbing for me! I get that it'd be 36 mg for the birds weighing aprox 4 lb, but I need to convert this to ml.
