What internal parasite is commonly found in chickens?

The correct answer indicates that roundworms and heartworms are both internal parasites commonly found in chickens. Roundworms, in particular, are a significant concern in poultry management as they infest the gastrointestinal tract of chickens, leading to issues such as weight loss, poor feed conversion, and overall poor health.

Heartworms, while primarily associated with dogs, can occasionally affect chickens, though this is less common. Their presence can lead to cardiovascular issues in the birds. Understanding these parasites is crucial for poultry caretakers to ensure the health and productivity of their flocks. Regular deworming and monitoring for symptoms are important practices in managing these internal parasites effectively.

In this context, ticks are external parasites, and heartworms, while sometimes affecting chickens, are not as prevalent as roundworms within poultry. This highlights the importance of identifying the right parasites that impact poultry significantly.
