I noticed a large number of the chicken poops (I have 1 rooster and 4 chickens) have tapeworm cysts visible. They all seem to be in good health and eating and drinking normally. They free range on a good sized plot. Some of their poops are truly covered with them. They are definitely tapeworm cysts as they move and compare against all the images I can find on the net. I have wormed with Flubenvet for the normal 7 days but now 5 days later the cysts are still visible so I am assuming the Flubenvet wasn't effective. I have some Levamisole that the vet gave me last year (although I normally prefer Flubenvet because it has no withdrawal for eggs) and thought perhaps to use this. I am concerned though that a) worming them twice so close together may make matters worse and b) I have read mixed reports about the efficacy of Levamisole. Any experience or thoughts would be really welcome!
