Where did you purchase your Oil of Oregano and how much are you adding to their water. I read that most birds turn their beaks up at drinking water with the oil in it, but yet I keep reading great posts and articles about the benefits of using it with turkeys.
I purchased it at a health food store and I don't add it to their water, I add 10-12 drops to 1/2 cup vegetable/canola or corn oil and then mix that into about 6 cups of feed, mix it well and let them have it.. I don't add any more feed until they finish this off You can also sprinkle in a couple TBSP of Cayenne pepper which I do... I give them this concoction once a week now.
