I think it’s because the backyard flock can pass the flu on to other birds in the yard, and to other people in stores like TSC if the owner wears their shoes there.I totally get that.
What I don't understand is why a backyard flock is a threat to him. It sounds like the wild birds particularly the water fowl and those birds that visit both the water fowl and his commercial flock are the danger.
Surely the backyard flock gets sick and dies and doesn't pass it on to anyone.
I will be the first to admit I am no expert on this, but I can't quite make sense of it to all.
