** E-COLI INFECTION **
Point Of Entry Umbilicus - Early Mortality (Omphalitis)
aka "Mushy Chick Disease, Navel infection, Yolk Sac Infection" (it goes by many names)
My experience was as follows: Within 1 day of having day old poults - 2 died, then another, then 2 more, AND it happened quick!! They were only 1, 2 and 3 days old. Fine one moment, dead the next.
Symptoms I noticed: head down, seemed lethargic, still walking however some went lame with bilateral leg swelling, toenails turned black - then death.
Clinical Findings: Culture results are consistent with Bacterial Septicaemia "aka" Blood Poisoning from E-Coli as the cause of mortality. The umbilicus was the point of entry for this infection. There was an abundance of Escherichia Coli in the "retained yolk sac" of all specimens. Port of entry for E-Coli was the open umbilicus in all cases.

E-Coli is always present in poultry environments and a normal part of the intestinal microflora in poultry.
Infection with E. coli, and most other bacterial species associated with omphalitis, can occur when an opportunity arises such as:
#1: excess contamination of egg shells
#2: cracked hatching eggs
#3: open / unhealed navels at hatch and poor sanitation
EARLY MORTALITY OMPHALITIS IN POULTRY

Because it happened so quickly at 1 and 2 days of age, it was the due to poor sanitization, poor quality, dirty hatching eggs it and was negligence at the hatchery.
