Reply to comment by Mamanfu in Why do poultry producers kill their stock when they get bird flu, rather than keeping survivors to reproduce? by poorbill

Your logic is right. But note farms kill their birds quickly after the flu is detected, infected or healthy. They cannot test all birds, so there could potentially be some birds that got the virus before and survived, or inmune ones. But because of the risk involved all are killed.
So there is little time to actually have survivors.

Ahh okay and another thing I hear being mentioned is it being SPREAD to another farm? How is it being spread if the birds are stationary.

Checkout u/mtv2002 reply higher in the post. Farms might have common personnel, equipment, visitors,etc. after all its a business. So many ways to spread the virus through various surfaces. Not a virologist, but air transmission might be possible.
