Question

where and why does the bird flow away​

Answer 1

nothing happened. The virus continued to kill chickens and to occasionally infect and sometimes kill people. But as the years passed, the number of human H5N1 cases subsided. There has not been a single H5N1 human infection detected since February

Answer 2

For a missing bird, place the cage near the site of the fly-away. If your bird flies out through your front door, for example, place the cage on your porch or doorstep. Whenever possible, hang the cage outside so that it appears just as it would indoors.
