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!
