Yes, this is a very dangerous situation for the swans. You need to construct some sort of feeder approximately 4-5 feet off the bank in which the swans can continually feed. This is why they are coming to your house, they want to eat. Swans feed throughout the day and night. Additionally, you want to place the feeder in an area which is lit so that the swans can watch at night for any predators along the bank. The reason that you want the feeder in the water and away from the bank is so that predators cannot grab the swans off the bank while they are eating. Keep walking them back to the pond until this behavior stops and do not feed them any more. Let them use the feeder. The Regal Swan
