It doesnt matter what type of worms a chicken has if you use Albendazole or Fenbendazole (Safeguard). Either product eliminates all types of poultry roundworms. I prefer Albendazole.Do you know that your chickens have worms and what type they have?
You want to find a dewormer that is the best fit for what you're fighting.
However, if tiny white tapeworm segments are seen in feces, use Praziquantel. Use either Equimax or Zimecterin Gold equine pastes for tapeworms.
