SCgamebirds, the best thing you could do here is to do a test on your own birds. Plain and simple. Have your birds poop tested for worms. If any are present, then use DE for what ever time period you feel necessary, then have your birds poop retested, and then come back here and post the results. If you are pushing something about DE that is coming from a vet, and you have not yet proven it to work in your own flock, then you can not tell people that it does work.
Ivermectin is also one of those things that may or may not be effective on internal worms as well.
So to get back to the original thread starters question on worming, Fendendazole, (safeguard) is a very safe wormer to use. It is used on many types of animals all around the world and is proven to kill all worms, with the exception of Tapes, safely in the body. Why mess with products that are not proven.
If someone that is new to birds here on BYC, and has a flock full of worm infested birds, why steer them to something that may not work. I have been hanging out in this quail section for nearly 3 years now. And I have seen so many threads here where their birds are dying from worms. New people are vulnerable and if steered in the wrong direction, they can lose their entire flock.
If you personally have a personal favorite, unconventional way to treat your birds, then that is fine. No one is telling you how to worm your birds. But lots of people are going to read this thread, and if they are new to this stuff, should be using treatments that are known to work. Later, after they have experienced more with their flock, they can experiment and gravitate in other directions.
All this being said, do a test. I am very curious myself, as I personally don't think DE does work internally. But if it does, I have learned something new. So, get on it!
