Here’s a simple device to make your life less smelly – it’s our Chook Poo Percolator. We also use it for Pigeon Poo.
All it is is two plastic spring water bottles. One stays completes, sits on the ground and is the recepticle.
The other has the bottom cut off of it and is flipped over. This is where the poo and water go. The cut off piece from the bottom of the container then becomes the cover for the poo.
In the neck of this one, I jam some mesh or cloth – any kind of filter material to stop the bigger items from dropping through.
You will need to rig up some kind of adaptor to allow the liquid from the top container to flow into the bottom. They cant just sit mouth to mouth because the openings are the same size and random drops will escape. You can tape them together to make a seal but then you have to remove it and retape it every time…that’s too much work for me!
I found a 32mm to 20mm reducer for PVC pipes hanging around in my junk box and it fitted beautifully.
To use, just join the two containers together.
Put the poo in until it is about 3/4 of the container. Then add water slowly until it is thoroughly soaked but not dripping much yet. If you skip this step, the water misses the edges and generally runs straight through the middle, leaving a lot of goodness unextracted.
Then add more water and it will percolate evenly through the dampened poo fairly evenly. You can add as much water as you want but do it slowly and in stages.
To concentrate the liquid, take the bottom container and pour the contents back into the top container (put the now empty one back, of course). You can do this a couple of times.
Letting the water percolate slowly through allows nitrifying bacteria time to begin breaking the leachate down into more usable forms and prepares it for better use on the garden.
Pigeon poo is quite variable. I get ours from under local bridges and from a demolished pigeon loft on a local farm. Your final results may be different from mine in constitution.
You will need to water it down too before using it on your garden , the final result is pretty concentrated.
Have fun. I reckon you could leach Guinea Pig, Rabbit or even Alpaca poo too.
