Well, you might think it is cost effective. I disagree. I think it is ridiculous. I know what kind of worm I am fighting. Roundworm. Fecal float for chickens.... That is a major cost of say thirty dollars, plus the trip to the vet, then a trip to another vet after they tell you they don't do fecal floats on poultry,.... (Do you have to collect it yourself or can you just scrape it off your shoe as a sample?) And as for your theory that the worms get more tolerant of the wormer... if I see worms in my chickens droppings, I would be very hurt... but I never do because I worm routinely sans fecal float)
A guy comes in and says he has worms in his chicken droppings.... I am telling him to buy wazine. You can certainly tell him to run the full gamut. But all this round and round makes chicken keeping alot harder than it has to be. I have been keeping birds since I was a young boy. It has not changed that much. Some people treat their chickens like a dog or other pet. To each his own. But I am not running to the vet I know exactly what I am doing.
