I have suspected for some time now that my chickens may have worms. Yesterday this fear was confirmed for me when I saw actual worms in the feces of one of my hens. Gross! Based on what Ive read since yesterday, I think that the worms that I saw were capillaria (hairworms) because they were tiny (less than half of an inch) and threadlike in appearance. The only reason I was even able to see the tiny things is because they were moving about in the loose stool. So, I am going to first use Wazine 17 - I know that Wazine 17 is only a treatment for roundworms and it will not be effective for capillaria (hairworms), but my chickens have never been wormed before and they are a year old. My understanding is that one must use Wazine for the first round, then after 10 days use a broad-spectrum wormer. My question, however, is which broad-spectrum wormer I should use in that second round? I assume that I will need one that will be effective for hairworms. I like what Ive read about Eprinex because it seems easy and there is no withdrawal period, but is it useful for treating hairworms? I am very new to all of this so any advice and suggestions will be greatly appreciated. Thanks.
