Yolk Sac Problems - Graphic Pictures

From 1-9-2014

This is a 4 day old duckling that I thought had wry neck, so I went shopping and bought all the vitamins and minerals that people suggested, but it passed shortly after I got home. Decided to send it to UC Davis for a necropsy and they determined that the cause of death was due to a yolk sac infection. Both E.coli and pseudomonas aeruginosa were found.


Here is part of the necropsy report that shows the bacteria and what drugs they were sensitive/resistant to:

So Is the ecoli common in newborn or something it picked up after hatch ? Was the navel not closed ? And was the feet supposed to be that color ?

E. coli and pseudomonas are two bacteria that are often found in chicks with yolk sac infections. The feet were supposed to be that color.

For future reference:
circle = umbilicus, arrow = vent area


Duckling shown (not mine) is two weeks old and probably had a yolk sac infection.
