I think that they should just let a bunch of goose hunters come in and take all they want! I mean, keeping the birds in a sanctuary is not going to solve the problem; the birds will keep multiplying. I think that this is sort of like trees. The tree huggers want to avoid cutting trees because they want to save the forests. But by not
cutting them, they are doing more damage to the forests. So, by not getting rid of the birds, there are human lives at stake or damage to airline equipment.
As to what to do with them....well, I think that there are plenty of hunters out there who might want to have a goose or two so open it up to hunting! Or maybe you could sell them to a restaurant or something like that. Just my opinion
