I haven't made any changes either as far as the bird flu goes. I live on property, so the girls still get to free range, they don't really like to wander as far as the fence line, so I'm not that worried about it. I do have issues with barn swallows nesting in their coop, but for the past couple years I've been knocking down nests, so it's less and less that try every year. So I'm just crossing my fingers too.
