What are Lash Eggs in Chickens?

Causes of Lash Eggs in Chickens

The primary cause of lash eggs is salpingitis, an inflammation and infection of the oviduct. This condition is usually caused by a bacterial or viral infection. The bacteria or viruses gain entry into the birth canal and move up the reproductive tract. Blood can carry infections from the abdominal sac straight to the oviduct, where they can spread from tube to tube.

Various pathogens can cause salpingitis, including bacterial infections such as Escherichia coli, Mycoplasma gallisepticum (causing Chronic Respiratory Disease), Salmonella spp, Streptococcus, and Pasteurella multocida (also known as Fowl Cholera). Other bacteria such as Enterococcus faecalis and Chlamydia psittaci may also be involved. Some viral infections, like Infectious Bronchitis, Newcastle Disease, and Avian Influenza, can cause damage to the reproductive tract of hens, potentially resulting in conditions like salpingitis.

The hen’s immune system reacts by trying to wall off the infection with waxy cheese-like pus. This pus may or may not contain yolk, albumen (egg white), egg shell, egg membrane, blood or pieces of tissue from the ovarian wall.

It usually signals a hormonal change and it is not uncommon to find your hen will go off lay soon after passing a lash egg, and she may or may not come back into lay.

Symptoms of Lash Eggs

Typical symptoms of salpingitis include the production of lash eggs and eggs with stress lines if the hen is still laying. The lash egg appears as an egg, but it is a build up of pus that is gruesome, squishy, rubbery, and covered only by a solid film. It is possible for this egg-shaped monstrosity to contain pus and parts of an egg white, yolk, blood, egg membrane, and oviduct wall tissue.

Other symptoms the hen may be exhibiting include:

  • Weight loss.
  • Depression.
  • Ruffled feathers.
  • Enlarged abdomen.
  • Soft shell, caseous or inspissated eggs passed.
  • Usually none other than finding the object in the nest box.

Look for behavioural and physical symptoms in your chickens if lash eggs are suspected

Treatment for Lash Eggs

If you find a lash egg in your chicken coop, it’s a red flag that your chicken may be suffering from a virus or bacterial infection. It’s important to consult with a vet to identify the exact cause of the lash egg. They may recommend an antibiotic or the inflammation may go away on its own. Antibiotics such as tetracyclines are used to treat lash eggs.

Other treatments may include changes in environment, diet, and hormone levels. Use of anti-inflammatory drugs (NSAIDs like meloxicam) and prostaglandins, like PGE2, can help the chicken’s oviduct squeeze out pus, lash eggs, or fluid that might be stuck in there. Use of lotus leaf extract can also be used to treat salpingitis.

Ensure you remove the infected chicken away from the rest of the flock and thoroughly clean and disinfect the coop with the aim of preventing infection in the rest of the flock. Make sure you practice good personal hygiene and wear gloves while doing this.

Prevention is better than cure. It’s important to make sure your chickens develop strong immune systems. Good hygiene is key. Keep the feeders clean, disinfect the water regularly, provide your chickens with a good poultry seed based on their age, and keep their coop clean. Chickens with a history of high egg production that are mainly fed a diet lacking sufficient vitamins and minerals are more susceptible to salpingitis. Also, obese chickens are more likely to develop salpingitis.

In conclusion, while lash eggs can be alarming to find, they are treatable and can be prevented with proper care and management of your flock. Always consult with a vet if you find a lash egg in your coop to ensure the best course of action for your hen’s health.

Ensure your chickens are getting a good quality feed and the proper nutrition
