LEV Wormer is a drinking water treatment for all worms except tapeworms. This makes it particularly useful for poultry infested with hairworm (Capillaria), crop and proventriculus worms (Strongyle) and especially for chickens with caecal worm (Heterakis). LEV Wormer is an effective immune stimulant for young chickens and pigeons but must be used at the recommended dose. Consult with Dr Marshall prior to using LEV Wormer as it has other beneficial functions for pigeon and poultry health.
