Feather Friday

Mom and Dad have a bird issue. They have hanging ferns on the front porch that the birds love to nest in. Mom and Dad try to discourage this, but the birds are just so determined. There was one fern that was dying because Mom and Dad didn't want to water the baby birds. Well, the baby birds were due to leave about the time that Mom and Dad were away last weekend. So when they got home they checked the nest and the babies were gone, but new eggs are already in the nest. So there's this dead fern that is driving them nuts now. So the question is, what to do next? If they move the fern to the side of the porch (about three feet at most), will the momma bird move with it? Can they put the nest in a new fern in the same spot? Can they put the eggs in a matching nest in the other fern (like I said, busy birds)? They don't want to harm the eggs, but they want a live fern hanging in that spot. Any advice is a help. Thanks!
