We did do myrrh in the water though and wormwood in the food, those are good for keeping parasites down, but you have to give it to em twice daily, the wormwood, and the myrrh every day in the water. Personally I would prefer the chicory option. I think its fine if you have only a very small flock but with a big flock I don't think it would be worth it. We did boil up wormwood and sage and let it infuse and then dose them with it, but again very time consuming and you have to do it more often than conventional. Garlic was also a very good one too!
