need dosage conversion help!

[mrsreaper2278]

How do I convert a flock dosage into at home use? The ratio is one packet (107 g. Or 3.77 ounces) to 100 gallons of water.
I would like to make 1 gallon at a time. How much mediction do I use?

Lacking a gram scale? A current U.S. penny weighs exactly 2.5 grams - cobble together a little hanging, or stick, balance - penny on one side/add med powder to the other until both sides balance, halve that pile of powder and add one of those piles to a gallon of water: So, instead of getting Exactly 1.07gm they'll get ~1.25gm.per gallon.

More exacting (maybe they list the med): https://sites.google.com/a/poultrypedia.com/poultrypedia/medicine-chart
