You're welcome. Wazine is only given in the water for 24 hours. There is a 14 day withdrawal time from finishing the Wazine. SafeGuard Liquid Goat Wormer or SafeGuard Equine Paste (and Panacur Equine Paste) are the forms of fenbandazole used in chickens. The Goat Wormer is a little easier to draw up in a syringe. The dosage is 1/4 ml per pound of weight given orally for 5 consecutive days to treat all difficult worms including roundworm, cecal or heterakis worm, gapeworm, and capillaria worm. So a 5 lb chicken would get 1 1/4 ml. If you have tested a fecal sample at your vet's office, you may only need to treat for 1 day to get roundworm followed in 10 days by a second dose, or for 3 days to get cecal and gapes. Since your chickens have cecal (heterakis) worms, you should treat for at least 3 days in a row. Egg withdrawal is 14 days after the last dose. I really prefer Valbazen sheep and cattle wormer, since it treats all chicken worms with 1 dose followed by a second dose in 10 days. Dosage is 1/4 ml for small chickens, 1/2 l for a 5 pound hen, and 3/4 ml for a large hen or rooster. Valbazen is found in fewer feed stores (Rural King and Southern States Co-op) but is easily found online. TSC carries Safeguard Liquid Goat Wormer.
