5.peace offerings placed in front yard
if you keep'em from nesting in your back yard, they will perfer the easy to get food placed in concealed areas in your front yard

Rabbit fencing to keep them out of the veggie patch. You may have to bury it down a bit. Some people use chicken wire.

I read somewhere once that rabbits don't care for marigolds and they avoid them. You can try planting some around your veggies, it may help.

Gotta fence it with chicken wire or something comparable, that the rabbits can't get through, and it has to go down enough to keep them from burrowing under.

Anyone have pictures of their rabbit fence? How deep and how tall should it be?
