Can Chickens Get Hookworms?

While chickens don’t get hookworms, there are a number of worms that can infect them. The most common kind of worm for chickens is roundworms. Adult roundworms are about 1 1/2 to 3 inches long and visible to the eye. The roundworms infect the chicken’s intestines, which can cause a number of symptoms and even death if left untreated. Your chickens may also have flatworms or tapeworms, though these are less common.

There are some signs if your chicken has a worm infestation. Look for a pale comb and a decrease in egg laying. Some chickens begin to lose weight and can become almost emaciated. The droppings may be watery or you may see actual worms in them. While it is hard to find vets that have expertise with birds, you can ask any vet to examine the droppings for worms.

Not everyone agrees on whether you need to worm chickens regularly. However, if you see one or more signs, it's probably time to treat. Treat the entire flock with a wormer approved for poultry. Usually the medicine is mixed into the drinking water. Read the directions carefully and take note if there is a time period to not eat the eggs after giving your chickens the medicine.

It’s easier to prevent a worm infestation than to treat one. One key to preventing worms is to keep the coop clean and dry at all times and don’t overcrowd your chickens. If one chicken has worms, they can be passed to the others through droppings in the bedding. Make sure your chickens are getting a high-quality food with adequate protein, vitamins and minerals. Also, wild birds can bring in worm eggs and other parasites, so consider placing netting over the pen to keep unwanted birds out.
