When a hen has an egg stuck inside her oviduct, she is referred to as being egg bound. Egg binding is a life-threatening condition that must be addressed quickly, preferably by a experienced poultry veterinarian. If the egg is not passed within 24-48 hours, the hen is likely to perish. Absent access to a vet, backyard chicken-keepers may have to take matters into their own hands in order to save the hen’s life.

CAUSES OF EGG BINDING

An overview of a hen's reproductive system is important in order to know where an egg may be stuck.

A hen’s uterus (aka: shell gland)  is the muscle responsible for squeezing the egg out of the vent. Since muscles require calcium to contract properly, if a hen has a calcium deficiency, the egg can get stuck in the uterus.

POSSIBLE SYMPTOMS OF EGG BINDING

  • Loss of appetite
  • Disinterest in drinking
  • Decreased activity
  • Shaky wings
  • Walking like a penguin
  • Abdominal straining
  • Frequent, uncharacteristic sitting
  • Passing wet droppings or none at all (egg interferes with normal defecation)
  • Droopy/depressed/pale comb and wattles
  • Presence of an egg in the oviduct upon exam
Frequent, uncharacteristic sitting

DANGERS OF EGG BINDING

Avoid treats in the summer heat when feed intake is reduced

PREVENTION

TREATMENT FOR EGG BINDING

  • A vet would hydrate the hen and administer calcium intravenously
  • At home, a warm bath can’t hurt, but probably won’t help
  • Apply KY jelly

To assess whether a hen is egg-bound at home, gently feel on either side of her vent with one hand (think: squeezing the cheeks of a cute kid). Offer vitamins and electrolytes in the drinking water. Even if she’s not interested in drinking, carefully try to get some water into her with a dropper or syringe. If she is too weak to drink, don’t force it.

At this point, put her in a crate in a darkened, quiet room. If a truly egg-bound hen does not pass the egg within an hour of these measures, the egg may need to be manually removed, which can be dangerous but is possible but proceed at your own risk.

Applying KY jelly to the vent can also help lubricate the cloaca to allow for ease of passage when the egg gets to that point (do not use olive oil, which can become rancid).
**DO NOT massage the vent, abdomen or oviduct!** A broken eggshell can mean curtains for the hen.

At this point, put her in a crate in a darkened, quiet room. If a truly egg-bound hen does not pass the egg within an hour of these measures, the egg may need to be manually removed, which is risky. Proceed at your own risk only as a last ditch, Hail Mary pass.

If she still hasn’t expelled the egg, and you don’t think she’s going to on her own, then you can move to manual manipulation. This only applies if she is still bright and not in shock. Palpate the abdomen to find the location of the egg and gently manipulate it in an effort to move it along. GENTLE is the key word here. If manual manipulation fails and you can see the tip of the egg, another option is aspiration, implosion, and manual removal.

“First, get someone to help you hold the bird very securely while you work (preferably not upside dwn). Then, using a syringe and a large needle (18ga.), draw the contents of the egg into the syringe. After aspiration of the contents, gently collapse the egg all around. You want to do this gently in order to keep the inner membrane of the egg in tact, which will keep the eggshell fragments together.

Stella was put to sleep due to severe egg-binding. She did not exhibit the typical symptoms outlined above, the only clues that she had a problem at all were a change in droppings, activity level and a hard abdomen.

Last, gently remove the egg. (Copious amounts of lubrication would be good here.) Go slow and try to keep the shell together (although broken). If all fragments do not come out, they should pass, along with remaining egg content, within the next several days.”

Would love to print this and keep in my emergency binder. It says I need permission. I won’t sell it or anything, just want it for my emergency kit.

How do you put a chicken down in the most humane way possible without a vet?
