Causes of Worms infestation in Chickens

There are so many ways a chicken can get infested with worms. Worms are everywhere in soil. There is no specific place for worms.

Chicken gets worms for so many sources. Sometimes they eat whole snails, slugs, grasshoppers which already contain worms in their body which goes directly inside the chicken’s intestine.

Most of the animals and birds eat seeds and feed from the ground. All worms live in the soil so the worm goes inside the intestine with chicken feed or treats which we love to give them.

Sometimes chicken eats droppings and poop of animals and humans. It is a major cause of worm infestation in chicken.

Another most important reason is wet litter in poultry sheds. Litter is the collection of chicken droppings in which flies sit and transmit worms from one place to another. Wet litter makes this transmission possible.
