I just gave all my chickens two ounces of Wazine 17 from Tractor Supply (TSC) in two gallons of water for ONE DAY . I'll dump that water tomorrow after 24 hours. Won't be getting any eggs for two weeks anyway because they're molting, days are shorter. In a couple of weeks I'll give 'em more light to make 14 hours per day. Meanwhile, I'm getting rid of all their roundworms. What better time. Heck, in ten days I might just as well give them the Valbazen (see below) and wait two more weeks before extending their daylight time; then my WORMING WILL BE COMPLETELY FINISHED for at least a year. Probably wouldn't have gotten but a few eggs anyway, so no big loss. THE FOLLOWING IS AN MS-WORD DOCUMENT WITH INFORMATION MAINLY FROM dawg53: ********************************** WORMING CHICKENS Joebryant BYC I haven't seen any worms, but I want to treat my chickens for them anyway because I don't really know what to look for. What is the easiest way to do it to be sure that I get rid of the most common types of worms? Is there a product that I can just add to their water for a couple of days? Dawg53 on BYC Are your chickens acting lethargic....not eating or drinking,not laying? These are common signs of possible worms. If your chickens are over 1 year old, never been wormed and free range...I agree they should be wormed. First worming, I would start with wazine17. Just follow the directions on the label. Toss eggs in the garbage for 2 weeks. Then in 10 days, reworm with a different wormer. joebryant BIG THANKS, dawg53, that's exactly what I was looking for. It can't get much simpler than what the directions say that I found when Googling: ETA You said, "...Then in 10 days, reworm with a different wormer." What do you recommend that I should use after ten days? http://www.drugs.com/vet/wazine-17.html "For best results, remove water in the evening (except during hot weather). Then, early the next morning, begin water medicated with Wazine-17. Provide medicated water only, distributed in waterers sufficient in number so that all birds or animals have access to water. The medicated water should be consumed in 1 day or less. Worming every 30 days is necessary to break the large roundworm life cycle. TURKEYS - Under 12 weeks of age: for each 100 birds, use 2 fluid ounces (60 ml) of Wazine-17 in 2 U.S. gallons (7.6 liters) of drinking water. Over 12 weeks of age: for each 100 birds, use 4 fluid ounces (120 ml) of Wazine-17 in 4 U.S. gallons (15 liters) of drinking water. Worm turkeys at 4-6 weeks of age and thereafter at 30 days, or as needed. CHICKENS - 4 to 6 weeks of age: for each 100 birds, use 1 fluid ounce (30 ml) of Wazine-17 in 1 U.S. gallon (3.8 liters) of drinking water. Over 6 weeks of age: for each 100 birds, use 2 fluid ounces (60 ml) of Wazine-17 in 2 U.S. gallons (7.6 liters) of drinking water. Treat broilers at 4 weeks of age and thereafter at 30 days, or as needed. Treat replacement pullets at 8, 12, and 16 weeks of age." Dawg53 On the 10th day after using wazine. I recommend a second type of wormer...you have the choice of the following: Ivermectin, Safeguard or Valbazen. All are off label wormers for horses,cattle or sheep, but can be given to chickens in smaller quantity, it's a matter of giving the correct dosage. I prefer Valbazen...it'll kill just about every kind of worm there is, including tapeworms. The other wormers are excellent wormers too, but wont kill tapeworms. You can read up on these wormers and choose which one you want to use and I'll give you the dosage for chickens. Joebryant BYC I'll use Valbazen since that's your preference. I have a dozen bbs Orpintons and six silkies. What dosage would they need, and does TSC sell it? THANKS AGAIN ETA If Valbazen will also kill tapeworm, is it necessary to use the Wazine first? Quote: ********************************* ETA: Here's a photo of a ONE ML/CC ORAL syringe; they come in various sizes. Your pharmacist will give you one or sell you one or more; they're very cheap. Mine sold me 20 one ml/cc like this one for $2.00 or ten cents each. Another pharmacist gave me a 3 ml/cc one.
