Sometimes we need to think of their best interest verses making them happy. When my daughter was 3 she wanted cake for breakfast and asked every morning for months. But for her own good she got oatmeal. :x :lol:
My point is that maybe a rabbit tractor would be best. I tend to over do things but haven't lost any of my critters to predators. knocking on wood And we have our fair share out here in the sticks.
A possible solution would be a rabbit tractor inside of a rabbit tractor. That way the coons can just reach in and grab you rabbits. I have fostered many racoons and they are smart and love puzzles. They will catch your rabbits and tear them apart just for the fun of it. Your buns might get luck and never get caught, but I personally would not chance it.
Racoons aside there are still many animals that would love a bunny dinner.
In your neck of the woods:
bobcats, fox, racoon, opossum, weasel, wolf, bald eagle, cooper's hawk, goshawk, red-tailed hawks, barn owl, great horned owl, and the snowy owl. Just to name a few.
You may know all this or maybe you don't I don't really know you as a person. But I do want your animals to be safe.
Just my 2 cents.
