This is what I did to their run on Saturday a few hours later it’s a muddy mess from the water. My yard isn’t level so all the water kind of pools in there towards the front. I do my best throughout the week to pump or pull it out but sometimes it’s useless. I also added a picture of the aftermath of the day before I cleaned it out
Here's some pictures of my holding pen for ducks. Sorry it's so messy! But what I did was build a brick square with bricks in one corner to set the water bowl on. The water mess all goes down into the hollow bricks and the rest of the pen is filled with deep bedding and stays dry.
This is the whole pen with the ducks we're getting rid of. They'll only be in here til this evening.
This is a close up of the water bowl corner.
And a close up of the safety pads pulled back. The drain holes need cleaned out at the moment.
If you can give your ducks a larger water bowl and area it becomes easy. With a big enough mini pond, they actually spend most of their time in the water...which keeps their feet healthy. Add some plants and little minnow type fish (I use mosquito fish) and water changes can be spread way out.
Here's a pic of my keeper ducks run. This is the one with a slight slant so water drains out the back.
Which I now know I need to clean of rocks better! My ducks say thanks Agnus!
I top off their water daily, but I don't need to drain and refill it often and theres a drain plug at the base to make it easy. I also set it up at the base of a huge tree, so when I do need to drain it the water isn't wasted...it keeps my tree healthy. I know when it needs cleaned because they start drinking out of their little water bowl that gets ignored most of the time. It's needing cleaned about once a month with 4 ducks. They even sleep floating in the water.
I do have to replace plants and fish weekly. The plants are stuck into a planter and create a tiny island they can climb out on. The plants are pretty well destroyed right now...lol.
I don't know if your ducks are holding pen ducks or keeper ducks...but creating drainage is really the key.
