preserve the birds, that are immune to it

I still don't like the everyone get measles version of this.

willing to really try this on a pilot as we build the safe perimeter around them to see if there is a way forward with immunity

"pilot with safe perimeter" seems reasonable, as long as safe perimeter works. Bird flu is endemic already, afaik. = "will remain a constant presence". It only makes sense for domestic chickens/fowls. It is not endemic yet in other animals/humans, and maximum quick containment seems like only approach to keep it that way.

Bird flu not being a problem in countries that have smaller flocks, seems a transformative solution.

I didn't like the rebuttals in my link above. One of them says that the best thing for you/chickens is "to have a central authority decide to cull you minimizing for a balance of cost and your pain, instead of giving you the chance/choice of either surviving, or far more likely, suffering before death." I would choose the 2nd option, but can only do so under central authority that has already decided what it prefers.
