I agree the first step is the make sure the ramp is easy for them to use. Make it as wide and long as possible. Make sure it's not smooth. They need traction. You can add small pieces of wood horizontally that keeps their feet from slipping back. Home improvement stores sell no slip tapes and paints. Or you can go really simple and add clean sand to exterior paint and paint the whole ramp. I did this on my old coop ramp and it really helped.
My current coop is on the ground so no ramp, but on the old one I had to heard them up every night. Currently, they sometimes go in on their own but most times I still need to heard them on. Usually depends on how nice the weather is. At first I had to train them to go in by walking behind with two long sticks. I would say "to bed, to bed" as I did it. I have a headlamp and would shine the light at the coop door as we walked. My coop door is automatic; it closes at sundown, so I would prop it open with a board. Now that they know the routine, most times I can just hold the door up, point the light at the opening, and say "to bed" and the ducks will go in.
It's much easier to heard them as a flock than it is to try to catch them individually. They are naturally inclined to want to stay together as a group.
