Worming with Valbazen--do I need to repeat?

[friend of chickens]

I heard of Valbazen for chickens through this site, and went ahead and wormed mine--or de-wormed them--7 days ago. The bottle says "may repeat in 10 days"...but I'm wondering if I need to repeat to get the egg and larvae stages as with other wormers? I know positively they had roundworms and tapeworms. I dosed them at 20 mg per kg of body weight. This medication supposedly works by inhibiting the worms from processing sugar. I hope someone can help me with this question. I don't want to over load them, but I also want to make sure I rid them of worms! Thanks ahead for helping me out!

Yes, I think you should probably re-worm in ten days. Seems that is a general rule with all wormers. Hopefully, someone will correct me if I'm wrong. Valbazen doesn't overload their systems with dead worms because of the way it works, I'm told.

Thank you speckeled -hen.. I just couldn't find anything online about re-worming with valbazen and I can find it all over the place with the other wormers...

Anyone know where I can look to find my answer in "written form"--so as to have some sort of scientific authority? I'd really appreciate it!

Pine Grove, who has been breeding chickens for ages and ages, says he uses Valbazen because of the way it works and it gets everything. I will be switching to it soon myself. It's hard to find anything in written form since none of the wormers, except Wazine (which only gets roundworms) are approved for use in poultry.


Here is First State Vet Supply's bottle instructions, which says to repeat in ten days:
