Why can't the bird die?
The reason why the birds that cannot be buried casually are mainly worried that the germs will be spread after rotting, but as long as it is buried deep enough, this will not happen.If birds die normally, you can also consider feeding other birds in need. Of course, if you are deep, you can also consider making specimens.It should be noted that the feathers of birds are not easy to rot, so there will be only these left after death.
