I've been looking for dewormer for my molting girls, with the understanding that fenbendazole is not to be used at this time. There is only 500 ml bottles of Valbazen and larger. Has anyone ever used Albendazole powder or capsules to treat for worms? I would put the powder in water and dose a piece of bread. Do you think that would work the same as using the suspension (Valbazen). Does the Valbazen have an expiration? If so, with my small flock of 11, I think that would be an excess amount to buy. Thoughts?
