Egg binding can quickly prove fatal—especially to smaller birds—so urgent treatment action must be taken. Even if you do everything correctly, there is no guarantee that the afflicted bird will be able to pass the egg and make a full recovery.
The most important thing you can do is provide the bird with warmth. Place it in a small cage at a temperature of 25-30 degrees Celsius (about 80-85 degrees Fahrenheit). Make sure cage is kept somewhere quiet, and is protected from draughts and anything else that could cause stress. If you don’t have access to a heat lamp, keep the bird in a room with central heating, a fireplace, or a space heater; but watch the temperature carefully. If possible, increase the humidity of the room with a humidifier, or simply by placing a dish of water beneath the cage.
When handling an egg bound hen, be extremely careful. Rupturing the egg while it’s inside the egg passage can cause mortal injury.
If the bird is already egg bound, providing calcium is going to do very little to help. Increasing calcium only helps to prevent re-affliction on subsequent eggs.
You can buy commercial calcium supplements that can be mixed into the drinking water or dripped directly into the beak. There are lots of natural calcium sources available too, such as cuttlefish bone and eggshells. You can give chicken eggshells to birds by thoroughly washing them, and then microwaving them on high for five minutes to kill any bacteria hiding in their porous surface. Make sure the shell has cooled before offering it to your birds.
It’s commonly believed that a rapid increase in calcium will strengthen the afflicted bird’s vent muscle enough to push the egg through. Although there’s no real evidence supporting this assertion, egg binding is a desperate situation and one should take advantage of even the smallest potential benefit.
In a last-ditch effort to help the bird pass the egg, you can try to lubricate her vent with cooking oil or a non-toxic personal lubricant. With larger birds, you may have success gentle massaging the vent area, but be extraordinarily careful, are rupturing the egg can be fatal.
Once the egg has been passed, a course of avian antibiotics can help to prevent infection.
Egg binding is generally a symptom of inadequate nutrition, so the first step you should take to prevent re-affliction is to improve your bird’s diet. Make sure you’re supplying calcium, fresh leafy greens, and green or sprouted seed.
