Pekin ducks wont use their pool ramp

[ducklovinfamily]

I have 3 adult pekin ducks and have just recently upgraded them to a step 2 hard plastic pool.It is a lot bigger and deeper than their last pool so we built them a ramp. The ramp is not at all steep and is 2-3 inches wider than the ducks,but they refuse to use it and cannot get into or out of the pool.
Today I put them into the pool and the stayed in there for 8 hrs before I had to shoo them out with a stick because they hadn't eaten since last evening. Here is a pic of the type of pool we have (not my pic, this is a pic found on Google, but same pool model). It has steps in the corners as you can see,and the ramp is setup right where those corner steps are.

Any advice on how to train them to use the ramp or modify the ramp to make them more comfortable?

I had the same problem with my ducks. My husband and I built stairs, and it took me a whole month to get them to finally all LEARN to go up the steps to get to the water. I used greens from my garden and sprinkled them all of the way up the stairs, and into the pond. I did this for at least two or three weeks, and they FINALLY learned.

I use cement blocks for them to use.
Mine love the pool and usually dont take the stairs at all. Even my tiny Call duck can jump into the kiddie pool.

Our one duck is shorter and we have just a little kiddie pool and we have boards outside of it to help her get in and she still cant I feel bad for her...sometimes shes in there but she really struggles

I struggled with this too. I found that my ducks really took to some large floor tiles turned upside down, The wide rough surface was perfect, one end propped up on a log. I now have them all the way around our kiddie pool.
