How much of each do you add to your water? There is so much information out there about natural remedies, it is hard to know what to do. I just ordered/received WormGuard Plus Broad Spectrum for Poultry (from Holistic Hourse.com) for intestinal worms and parasites. (I am using it for prevention.) It has DE, whole flax seed, and grape seed extract. I added it to their feed, as per instructions. I was also advised to use 1 tsp of apple cider vinegar per 1 gal of water to help prevent worms. While I love the thought of going natural with preventatives/cures, how does one know if any interaction will occur when using many of the products/ingredients together?
