You can't get to these people with pitchforks. You can't get to these people at all...all you can do is cultivate a family and a life that is immune to this kind of crap and all the other (((kinds))) to. The only airport I would want to live near is a secluded gravel strip next to a farm

In summary, this patent is stating the following:

Coronovirus, which already exists in the wild, kills lots of chickens, so it would be useful to make a vaccine that could be used on a chicken when it is still in the egg. They present here (in this patent) a method of making a vaccine for Coronovirus by manually editing the DNA of Cooronovirus to make it last less long and cause less damage after infecting a host. This allows it to be used on a chicken egg where other methods of making a vaccine would not be effective in an egg because they would be destroyed by antibodies left by the egg's vaccinated mother.

It proves that whoever wrote this patent is well versed in the art of writing custom DNA for delivery via Coronovirus so they would have the MEANS of starting a Coronovirus pandemic, but this document does not demonstrate any motive or opportunity. Only thing they claim to be doing here is trying to save the lives of delicious chickens.
