I'm hoping to add ducks to my homestead next year. Was thinking 3 females.
Is there a standard ratio of how many gallons of pond water needs to be provided per duck?
If you have a small flock, I'd love to know how many you have, how big your pond is, and how often it needs to be cleaned/refilled.
The goal would be to drain the tub/pond though some kind of filter and use the water to water my berries. I've been trolling lots of posts about water re-use, still not exactly sure how to accomplish this yet. Straight though drip would clog the emitters. If you're doing something similar, would love to know how its working!
Allright here we go!
There is no "formula" for ducks go gallons but use this as a general guideline. The more ducks you have, the faster they will mess up the water. I will let people with kiddie pools go into more detail, but with three ducks you will be emptying a vessel of that capacity twice a day. The more gallons you have, the less you will need to change the water.
Here is my experience.
At first I had a 50 gallon pond and two ducks. Without filtering I had to change the water every 2 days at most, daily changes would have likely been better. I then created a sediment filter (among others) that successfully filtered out the duck poop. With that filter and a 55 gallon capacity, I could go about a week before I needed to do a 20% water change.
Now a word on filters..........the good news is I was doing less water changes, the bad news is I was cleaning the filters every week. This was a win because my intent was to reduce water changes but there was still a fair amount of work, just no wasted water. Now, back to ponds.....................
Two weeks ago I installed a 185 gallon pond and a large sediment filter. I have yet to require a water change with the two ducks pooping in there 24 hours a day. I created a super huge sediment filter with a large drain so I could easily drain the duck poop with the twist of a valve. Meanwhile, back at the small pond I was unsatisfied with the small setup as the big pond was doing so well. I added 55 gallons of water, through the use of a 55 gallon drum, and copied the sediment filter that I used for the large pond. This brought the capacity of the small pond to 140 gallons and the results have been good so far. I have yet to require a water change on either pond (other than backfilling what the ducks drink and splash out)
NOW, that said, my intent with the filters was to prevent water waste as I live in Southern California and that objective was achieved. My ponds are not crystal clear but they are clean enough for the ducks and the water coming out of the filter is crystal clear and provides clean drinking water for my fowl friends. I have a catch basin to provide a clean fountain for the ducks so they have a clean source of water. Recently I added four ducklings, but they don't swim much and by extension don't poop in the water.
So to answer your question..........if you are willing to change out the water 1 - 2 times a day then a small kiddie pool or 20-30 gallons will serve you fine. For a bit more money (not much) you can create a sediment filter on a small pond (50 - 70 gallons) that you will have to change the water weekly.
P.S. The drain in my filters takes the liquid fertilizer directly to my plants and trees so it is not wasted.
