Whoa, a personal attack! Isn't this against the rules?

Anyway, nothing of what you say about me is true. Back on topic - it's not about me, it's about the diversity of opinions solicited by the OP in the first post of the thread. Also, posting links is very important and the way to prove objectivity.
Back to the comedy routine, I wrote a little sketch:
Members of the public with worms (chorus) : "We got worms! We got worms!"
Modern medicine (wearing nice white labcoat and smiling reassuringly): "Don't you worry your pretty little heads, I have something for the worms, but I'm an honest person and must mention that there could be side effects, some of them severe."
@dawg53: "Thank you!"
@Sue Gremlin (professional parasitologist): "I am not a big fan of throwing dewormer at animals as a matter of course. [...] They will often become reinfected quickly since they eat everything. If they are healthy and happy, there's no need, IMO, to evacuate the worms most of the time. In fact, I wonder sometimes if this causes more harm than good."

"I don't think "no worms" is a realistic goal for livestock, nor do I think there is a lot of value in it. It depends on what kind of worms, and how many."

@BugStalker :"I hated using fenbendazole in the past and I am worried for my 10yo roo."
@Dukes7779 (OP): " Looking for pros/cons of each as well as reasons/literature supporting your views."
@Saaniya: "after dewormer I use 10 day liver Tonic for detox"
@Shadrach: "Worms are not a problem until they reach a certain amount generally speaking. Routine worming is not only a waste of time but it also reduces the effectiveness of the medication over time. The worms become immune to it. I worm when a hen looks sick and I've had a fecal float done."

@chkva: "When you worm with medication, you can't eat the eggs. I feel like giving meds for no reason, isn't very healthy."
@sittychick: "I'm taking a class on Homeopathy (an alternative form of medicine). Its safe, natural."
@cottagecheese: "You do good work, modern medicine (generally speaking), but I think I'll sit this one out. I've got Cina up my sleeve."
