BIG THANKS, dawg53, that's
exactly what I was looking for. It can't get much simpler than what the directions say that I found when Googling:
ETA You said, "...Then in 10 days, reworm with a different wormer."
What do you recommend that I should use after ten days?

"For best results, remove water in the evening (except during hot weather). Then, early the next morning, begin water medicated with Wazine-17. Provide medicated water only, distributed in waterers sufficient in number so that all birds or animals have access to water. The medicated water should be consumed in 1 day or less. Worming every 30 days is necessary to break the large roundworm life cycle.
TURKEYS - Under 12 weeks of age: for each 100 birds, use 2 fluid ounces (60 ml) of Wazine-17 in 2 U.S. gallons (7.6 liters) of drinking water.
Over 12 weeks of age: for each 100 birds, use 4 fluid ounces (120 ml) of Wazine-17 in 4 U.S. gallons (15 liters) of drinking water.
Worm turkeys at 4-6 weeks of age and thereafter at 30 days, or as needed.
CHICKENS - 4 to 6 weeks of age: for each 100 birds, use 1 fluid ounce (30 ml) of Wazine-17 in 1 U.S. gallon (3.8 liters) of drinking water.
Over 6 weeks of age: for each 100 birds, use 2 fluid ounces (60 ml) of Wazine-17 in 2 U.S. gallons (7.6 liters) of drinking water.
Treat broilers at 4 weeks of age and thereafter at 30 days, or as needed. Treat replacement pullets at 8, 12, and 16 weeks of age."
