What type of worms do chickens get?

Roundworms, hairworms, tapeworms, caecal worms and gapeworms are the most common. They live in the gut or respiratory tracts of the birds. They can be picked up from free-ranging or even inside the coop if the coop is not kept clean and disinfected regularly. The most common way for the worms to spread is through the droppings of the chickens of from wild birds.
