The majority of my flock is three years old and I have never wormed them. I have been looking for evidence of worms in all the gross places for the past few weeks and have not seen a single worm of any type. However, some of the girls are feeling thin to me so I think I will take the plunge and give them some type of wormer. I have read NUMEROUS posts on this subject to find the best solution and everyone has different advice. Not sure what to do at this point. Since I have not seen worms of any type, what is the best course for now? I don't want to give up several weeks' worth of eggs if I don't have to. Yes, I have read about all of the "natural" methods and would prefer to use them, however if they do have worms I want to get them taken care of and then use some of the other methods in between. I'm a believer in both types of medicine. All that being said, since I don't know what I'm up against worm-wise since I have not spotted any, what is your advice? Based on some of the posts, I am thinking Wazine then Ivermectin, both followed by the dietary goodies that should follow to right their gut. Will that take care of whatever they might have?
