I'm with RR. My opinion is that there is no need to treat, unless there is an issue that needs to be treated. As for the "issue" of worms: We need to be aware that internal parasites are not an issue if it's a light load. A common statement is: 10% of the animals in a flock or herd will carry 90% of the parasites. IMO, if we continually cull the weaker animals from our flocks, we will be removing the parasite carriers. Now, I realize that my "chickens are livestock" management is vastly different than the "chickens are pets" management style. So, it comes down to an individual decision based on the flock owner's goals.
As for Cassport's ?: If I found a pile of poo full of round worms, I would have to take other factors into consideration: How is the flock acting? Are there any birds that I should have already culled? If the answer to the latter question is Yes, that would be my first step (along with a thorough dissection of intestines and amateur autopsy looking for abnormalities). I would then probably go the herbal approach first, followed by a fecal float with a good cross flock representation of poo. Then... based on results of that... I'd make the decision to treat or not to treat.
Also, if internal parasites were found, I'd have to take a close look at my management practices: What do I need to change up to provide a healthier environment? Decrease flock size? Perhaps move birds to a new temporary run, giving the old run time to "rest".
