Why are you forced to cull birds if they have avian influenza? They often do not use humane methods and it rarely affects humans. Examples of methods to cull them are smothering them with foam, shutting off ventilation, filling the air with CO2, raising the heat. Most of those are slow and painful deaths. Moth of the deaths are caused by culling rather than the actual virus. Perhaps birds could actually develop an immunity if given the chance to adapt. Humans are not murdered if they are sick nowadays, so why should our poultry have to suffer these cruel practices? People rarely even give the birds a chance or even try to experiment with different treatments. It doesn’t really seem very effective when wild birds will still spread diseases. I have heard of some people successfully having birds recover, but I am not sure how reliable that information is. I’m not sure if this is the right forum for this.
