I have tried Rooster Booster wormer, tried ordering another wormer that has no withdrawal from Australia and they can't export, and DE and I'm at my wits end. I am trying to find a dosage and a for sure protocol for the hens. I have 14 Isa Browns. I have SEEN evidence in the poo of definite roundworms. I have read to Wazine in the water and then follow up with Valbazen. Then I read Valbazen then follow up with Valbazen. Here's my thoughts. I have NO idea how I'd individually worm 14 hens with a syringe and isn't it for 3 days? I am ok with just using Wazine, but my luck they have other worms and I'll have to do this ALL OVER AND THROW AWAY ALL THE EGGS. If I do Wazine only is this the schedule- Day 1-put in water for 1 day? Or should I do a couple of days to make sure they drink it? Throw all eggs away. Day 10-Treat again in water if using Wazine or can treat with bread or syringe with Valbazen Throw away egg for 14 days after final treatment. How many days do I treat for initial treatment? And for second dose? Thanks, Sonya I am buying Wazine today. I have seen evidence of worms for over a month. (only see them in one pile each time) so I need to get on this. Thanks in advance for you help! Vets and stores around here just DON'T HAVE ANSWERS FOR ME!
