Intestinal worms can affect the general condition of hens and the flock’s performance. However, visible signs alone cannot confirm their presence: other problems can cause similar symptoms. The poultry farmer must therefore observe the flock carefully and seek advice from the local veterinarian in the event of any abnormality.
What signs should you look for?
Watch for hens that lose weight despite having normal access to feed, have less smooth plumage or seem less active. A drop in laying rate, irregular growth in young birds, reduced appetite or unusual droppings can also be cause for concern. Sometimes, a bird appears weak or stays apart from the group.
These signs do not prove that worms are the cause. Make a note of when they started, the number of hens affected and any changes observed in the droppings or in feed and water consumption. These observations will help the veterinarian assess the situation. If a hen’s condition deteriorates or several birds are affected, contact the veterinarian without delay. Do not choose a product or treatment method yourself.
Reduce opportunities for exposure
The eggs of some parasites can end up in the environment and be swallowed by birds. Keeping the poultry house and ranging areas clean is therefore essential.
- Remove droppings and soiled litter regularly. Replace damp areas, especially after heavy rain or when water seeps into the chicken coop.
- Keep drinkers clean and check that they are not leaking. Raise feeders to limit contamination by droppings and litter.
- Avoid waterlogged ground and accumulations of droppings in places where hens often peck. If a range is badly damaged or wet, organise access to the available areas to reduce the concentration of birds in the same place.
- Clean equipment before moving it from one poultry house or flock to another. Limit unnecessary entry and provide footwear reserved for poultry farming.
- After a flock leaves, empty and clean the poultry house, then leave it empty before the next birds arrive.
Daily observation makes it possible to spot changes earlier and provide useful information to the veterinarian. In Côte d'Ivoire, pay particular attention to litter maintenance during rainy periods. At the slightest doubt, have the flock assessed by your local veterinarian and strengthen hygiene practices around the chicken coop straight away.
