You probably can use pigeon manure as a plant food.
However, I suggest that some caution be exercised when handling any kind of manure. Wild Bird Excrement might contain harmful Bacteria.
Therefore, the use of gloves and a dust mask would be recommended
A proven approach would be to make an Organic Soup.
Take:
2 tablespoons organic manure 2 teaspoons dolomite lime Add this to a pint of water in a plastic container, stir 2-4 times daily.It takes about two weeks for this starter batch to calm down.
2nd suggestion, test the pigeon manure (soup) as a plant food on a few plants assuring or proving the safety of the concentrate.Starting use: stir the soup and depending on if you want the larger dissolved solids in your dilution, wait between 30 seconds and 2 min. The heavy solids rapidly fall to the bottom. The longer you wait the less solids in the mix.
Dilution:
1 teaspoon to a Quart (or to a Pint) of water depending on the size and energy of the plant.From there as the stock feed concentrate is used, you replenish the depleted mix with water (daily to maintain liquid level) & new feed (weekly or bi-weekly) along with other organics to aid in the breakdown of the nutrients.
