[edit] Introduction
This is a parasite of turkeys, and occasionally chickens, pheasants and game birds. This condition has high and mortality in turkeys. Although chickens are relatively resistant to the condition, significant disease has been seen in breeding chickens and those that free-range. The parasite is ingested in the ova of Heterakis worms or as larvae in earthworms or faeces and there is an incubation period of 15-20 days. A Turkey shed is a perfect breeding ground in spite of the fact that it is difficult to infect birds orally with unprotected parasites. Having both chickens and turkeys is likely to increase the risk of this disease in turkeys.
[edit] Symptoms

[edit] Treatment
