Thus, chickens can be infected carriers for a long time because they are not removed or medicated by their owners, and they do not die or stop eating/defecating. H. gallinarum eggs can remain infective in soil for four years, a high risk of transmitting blackhead to turkeys remains if they graze areas with chicken feces [5] in this time frame.
H. gallinarum has a direct lifecycle involving birds such as chickens, turkeys, ducks, geese, grouse, guineafowl, partridges, pheasants, and quails as definitive hosts. Eggs of H. gallinarum are passed in feces by the host. At optimal temperature (22 °C), they become infective in 12–14 days and remain infective for years in soil.

Turkey poults, baby chicks and pheasant chicks are most susceptible to infection. Turkey poults usually develop gapeworm signs earlier and begin to die sooner after infection than young chickens. Lesions are usually found in the trachea of turkeys and pheasants but seldom if ever in the tracheas of young chickens and guinea fowl.

Feather pecking is a behavioural problem that occurs most frequently amongst domestic hens reared for egg production, [1] [2] although it does occur in other poultry such as pheasants, [3] turkeys, [4] ducks, [5] broiler chickens [6] and is sometimes seen in farmed ostriches.
