Oviductal Rupture
Oviductal rupture is a serious reproductive condition in hens. Although it sometimes occurs secondary to dystocia or oviductal disease, it is usually caused by inexperienced poultry owners administering their birds' hormonal drugs to help them pass an egg. These drugs include oxytocin, prostaglandins, arginine vasotocin, and ovocentesis.
Suprelorin®, Virbac is used 'off-label' to stop ovulation (egg production) in hens.
Salpingohysterectomy (spaying)
The surgical removal of the entire oviduct of the chicken.
Antibiotics
Supportive care
Isolate the bird from the flock and place in a safe, comfortable, warm location (your own chicken "intensive care unit") with easy access to water and food. Limit stress. Call your veterinarian.
