Egg drop syndrome ’76 (EDS ’76) is an atadenovirus-induced disease characterized by the production of pale, thin-shelled, soft-shelled, or shell-less eggs by apparently healthy laying hens.
What are the symptoms of egg drop syndrome?
Signs include loss of colour in pigmented eggs, thin-shelled, soft-shelled or shell-less eggs and a reduction in production up to 40%. Watery albumin and a reduction in the size of the egg, inappetance, dullness and diarrhoea may occur.
Is egg drop syndrome contagious to humans?
Antibodies against the egg-drop syndrome 1976 have been detected in wild Canada geese (Bonner et al., 2003 and Bonner et al., 2004). The virus can also be transmitted via humans, needles and egg trays. The lateral spread of the disease can be slow.
Can you cure egg drop syndrome?
There is no treatment for EDS. Egg drop syndrome is a viral disease that results in decreased egg production in an otherwise healthy flock. The outbreaks can last from 4–10 weeks and can result in a 5–50% drop in egg production. Egg drop syndrome virus can be transmitted both vertically and horizontally.
What causes drop in egg production in poultry?
Hens may lay fewer eggs due to light, stress, poor nutrition, molt or age. Some of these reasons are natural responses, while others can be fixed with simple changes and egg laying can return to normal.
Why does my chicken keep laying eggs with no shell?
Why do chickens lay eggs without shells? It’s mainly caused by a calcium deficiency. Calcium makes up a large portion of the eggshell, so your hens need a lot of calcium to lay eggs. Without enough calcium, their bodies will either produce very thin shells or be unable to produce a shell at all.

What is a defective shell gland in chickens?
The eggshell’s pigment is deposited in the shell gland pouch. If the shell gland is defective in any way, the quality of the pigment is affected. While it’s not uncommon for older hens to lay pale eggs, younger layers whose eggshells are abnormally pale might be suffering from infectious bronchitis.
What is false layer syndrome?
False layer hens look and ovulate normally but do not produce eggs. Typically, hens appear healthy, with fully developed secondary sexual characters and an active ovary, but a nonfunctioning oviduct. They are found at the peak of egg production.
What is EDS in poultry farming?
Duck adenovirus 1 (DAdV-1) is the causative agent of egg drop syndrome (EDS), which results in depressed egg production accompanied by the production of abnormal (soft-shelled or deformed) eggs. The disease was first experienced in Europe in 1976, and soon became known worldwide.

What is a fairy egg from a chicken?
A fairy egg forms when a piece of reproductive body tissue or a blood clot separates from the oviduct wall. The hen’s egg-producing glands don’t know that this tissue is not a yolk, and proceeds to create albumen (egg white), membranes and a shell around it, as it travels through the oviduct.
What can you feed chickens to make eggshells harder?
Switch the flock immediately to a laying diet which has 3.5% or more calcium when you see the first egg laid by the flock.
