Internal parasites (worms) can affect all types of poultry. They are found throughout the world and can cause production losses and increased mortality in flocks. Commercial poultry producers use confinement to help prevent infections from internal parasites. Free-range backyard flocks may acquire these parasites as they interact with the environment.

Recognizing and Preventing Avian Pox in Small Flocks (FS-979)
Avian pox is a disease that affects chickens and many other bird species, particularly in backyard, hobby, and exhibition flocks. It occurs in two forms—dry and wet—causing skin lesions, respiratory issues, reduced growth, decreased egg production, and occasional death in severe cases. The disease spreads through mosquitoes and contact with contaminated scabs, but can be prevented through vaccination. Avian pox poses no risk to humans, and early vaccination and biosecurity practices can help limit its impact on flocks.
