Dawg - I have read several of your posts on these boards and you sure do seem knowledgeable on this topic, which is great! I hope you don't mind a question or two - I'm a new chicken mom and I want to do a good job. At least one of my chickens has roundworms, and I have ordered a bottle of Wazine (at a ridiculous price, off of eBay) to treat it. I know there are other options, but I am overwhelmed at the thought of having to get each chicken at night, bring it in the house and figure out how to dose them individually. The idea of just adding something to their drinking water is worth the money to me, and I will follow your advice above. My specific question is, my girls are still young, 14 weeks, and aren't even laying yet. Is there any danger to them with this product at their age? I know I won't have to worry about the eggs, since they aren't even laying yet! Thanking you kindly for any advice you may offer.
