Intestinal Volvulus

Intestinal volvulus is considered an emergency situation that requires immediate veterinary care. It occurs when a loop of the chicken's intestine twists around itself, causing a bowel obstruction. This condition is most common in young chicks, due to twisting around the yolk sac. Intestinal volvulus has also been reported to occur in older birds, as a secondary result of enteritis or abnormal peristalsis caused by parasitic worm infestation or coccidial infection.

Intestinal volvulus causes the bird severe pain and progressive damage to the intestinal wall, with accumulation of gas and fluid in the portion of the bowel obstructed. Without prompt action, this can result in necrosis of the affected intestinal wall, acidosis, and death.
