I would also go for more of a neutral so the geese pop more. But if you like the red, I would go with #3 as it has the most contrast with your red geese. Your three reds contrast nicely with all the other geese, so I would make the decision on which looks best with the red geese. Of course you have the best view for that.
Just my thoughts. I am sure it will be beautiful. Geese are one of my faves.....would love to see this completed!
