We have a black horse trough we are planning to use for the duck pond until we can fence in our current pond area. We now have a rubbermaid bucket as their pond. Do we need to dig down the trough for the ducks to walk into it, or can we build a ramp and platform for the trough? Will the ducks use the ramp? We have a 2x6 as a ramp to the rubbermaid bucket pond and they don't use it. Not sure if it's because the ramp is too skinny for the Pekins, or if it's something else. What's your duck pond/duck ramp experience?
