Here is a link to a journal article:

Summary of study findings and how a flock was managed:
1. There was a high incidence of worms in this 1 year old flock, maintained on litter. Incidence:
o Ascaridia galli (roundworms)73% adults; 80% larvae,
o Heterakis gallinarum (cecal worms)100% adults; 73% larvae
o Capillaria obsignata. (capillary or thread worms)100% adults; 100% larvae
o Raillietina cesticillus (tapeworms)53%
2. There were no adverse effects of albendazole treatments on bird appearance, behavior, apparent appetite, and weight gain.
3. Good control was seen at 10 mg/kg for all worms except tapeworms, which required 20 mg/kg for control.
4. Through other medical websites, I found that albendazole is used to treat humans with worm infections.
5. Conclusions:
o Since there is a very high incidence of worms in chickens raised on litter, I plan to worm my chickens 2 times per year, or more frequently if I observe worms or weight loss.
o I will use 10-20 mg albendazole/kg body weight, which translates to:
- 2 pound chicken ~0.1 ml Valbazen
- 4 pound chicken ~0.25 ml Valbazen
- 7 pound chicken ~0.5 ml Valbazen
Still we only worm with chemical wormers when a fecal test shows positive and we test twice a year. We use a preventative the rest of the time called Verm-X. We are in AZ where it is very dry and can't remember the last time we had worms in either flock....
Southerndesert, this is a very good article, I bookmarked the website. The article mentions that the 3 or 4 most common worms found in chickens are roundworms, capillaria and cecal worms, also tapeworms. I guess the part that confuses me is that this article has shown tests with albendazole killing those 4 common worms. But the manufacturers label on albendazole does not mention them, just other worms, (except for tapeworms). I wish they'd all get their facts straight.
The best thing I've learned here is that I've been treating with Wazine for 4 years, and not realizing that there are other worms I need to kill. I wonder if my chickens have suffered from that. I don't know. But now I will be using more affective wormers, like Valbazen, fenbendazole, and Pyrantel Paomate, and kill all the little suckers. I live in Florida and for sure the worms proliferate here.
I also have to say that it shocked me when a 10 week old chick I had pooped round worms right in front of me. I didn't think they were old enough.
