It is. "Bird flu" isn't transmitted by eggs to humans. Besides, you know what happens to a sick hen if you leave her alone? She either dies or gets better. In either case, she's immune to that strain of the flu.
Apparently, it doesn't work that way. The surviving birds may still harbor the virus and spread it to their offspring, who wouldn't necessarily have a genetic immunity to the virus. It's also a mutation prone virus with a risk of it jumping to humans.
