In most cases, deformed eggs are safe to eat so there’s no need to throw them away. Most hens will not survive more than 6 months with Salpingitis. By the time one is discovered, the problem has been raging inside the hen for months and the prognosis for recovery is poor. Lash eggs/Pus Coaguleggs are bad news for the hen. They may recommend an antibiotic or the inflammation may go away on its own. They can determine what likely caused the lash eggs and direct you towards the best treatment. Hens that produce lash eggs should be treated by a vet.

What do you do if your chicken lays a lash egg? Shells with wrinkles or ‘checks’ in the shell are known as ‘body check’ eggs. Misshapen eggs can also be caused by infectious bronchitis or egg drop syndrome, both of which are cause for alarm. Nord Vet Med.In senior layers, oddly shaped eggs can result from stress or, if they are a regular occurrence, a defective shell gland.

The sensitivities of various serologic assays, including agar gel precipitin (AGP) assay, ELISA, Hemagglutination-inhibition (HI), and serum neutralization, are similar for detecting antibodies to EDS virus. Reduction in production with the occurrence of depigmented, soft-shelled eggs in the absence of other clinical signs should trigger consideration of EDS. EDS will need to be distinguished from Infectious Bronchitis (by absence of respiratory signs and typical misshapen eggs), Newcastle disease, Avian Influenza (by absence of illness), and severe vitamin D3 deficiency. Clinical signs are mainly associated with egg production. The first sign of infection with EDSV is a change in the color of the egg, quickly followed by production of smaller-the-normal eggs, shell-less, thin-shelled, or soft-shelled eggs, and either a rapid or extended loss in egg production of up to 40%.

In infected embryos or young birds, DAdV-1 is latent until onset of laying eggs. The primary site of replication of the virus is the pouch shell gland. The virus is spread both vertically and horizontally. Ducks and geese are the natural hosts for the virus, and are often asymptomatic carriers. Egg drop syndrome virus (EDSV) or Duck adenovirus-1 (DAdV-1), originated in waterfowl and likely introduced to commercial chickens through a contaminated vaccine. The disease results in egg quality defects in the eggs laid by infected hens. Egg drop syndrome (EDS) is an infectious disease caused by an adenovirus which mainly affects laying hens.
