Will bring in fertile eggs from a different flock cause disease?

hi
My question is if I bring in fertile eggs I bought from a different flock, could they be carrying disease from their original flock?

I had a flock of silkies a few years ago and bought I a new male and 2 more females and they were infect with something and wiped out my whole flock. Now its a few years after and what to start a new flock, but I'm afraid bring in birds from different places could do something like that again. So I was thinking about getting 2 - 3 hens from the same place and hatching the rest from fertile eggs I bring in.

Recently someone here on BYC contacted me with a request I sell them some eggs from my flock. I had to turn them down, explaining my flock carries the lymphotic leucosis virus which passes vertically from hen to egg, as well as horizontally from rooster to hen through sexual contact and hen to hen via dander and feces.

The biggest danger is not that I would sell eggs from my infected flock, but that someone who has no clue their flock is infected due to the virus being undetectable unless a chicken becomes symptomatic and dies and the flock owner then gets a necropsy to determine cause of death would unknowingly sell you their eggs declaring their flock disease free out of ignorance.

The only way you can be assured the fertilized eggs you buy are disease free is to buy from a certified breeder whose flock has been tested for these diseases and has passed inspection.

Ok, Thanks for the info. Much appreciated.

This is an interesting question I would be interested in hearing more about this

Here is a concise compilation of all of the diseases of poultry that can be passed to other chickens and also to eggs by the hen that lays them, infecting the embryo inside. https://en.engormix.com/poultry-ind...ertically-horizontally-transmitted-t36575.htm

On the chart, note the column that states how the disease is transmitted. The ones that state "vertical" transmission indicates those that can infect fertilized eggs.
