Question about organic blueberry fertilizer, safe ingredients?

[Jenbirdee]

I have about 10 blueberry plants in pots on a staircase that the ducks hide under sometimes and I want to fertilize them but I realize when it rains or I water them, the ducks will be dabbling some fertilized water… so here’s the ingredients… Poultry manure, soybean meal, seabird guano, sulfate of potash, fish bone meal, crab shell meal, and shrimp shell meal. No sludge, fillers, or additives.​

Your ducks will be fine.
