Things You'll Need
Raft
Traffic cones
Duck food
Floating duck feeders can be helpful if you have a large amount of ducks and a pond. Instead of feeding them on land, which would require sufficient space for the ducks around individual feeders, leading to potential conflict around each feeder, you could feed them on a large floating feeder on the pond, allowing for them to eat as they like without as many difficulties. Building a floating duck feeder is a simple chore that will improve the quality of your duck feeding experience.
Examine your raft. If it is the kind that requires inflation, inflate it. If it's a simple wooden raft, no further preparation is necessary.
Fill the raft with duck food. You want to have enough duck food on the raft to satisfy the birds, but not enough to cause the raft to sink. The exact amount required depends on how many ducks you have and how frequently you are feeding your ducks.
Invert the traffic cones and fill them with duck food. This is a good solution if you have less birds and a raft would be more food than you need.
Tips
If it rains, you will need to pull the feeders back in as wet food can become moldy.
Feed only as much food as the ducks can consume in a reasonable period of time.
