Isn't duck poop water wonderful! Not so good for root plants tho, they suck up that flavor, but good for all things that grow above ground. Have some stuff in the back barn where we kept 70+ chickens about 3 years ago, ought to be primo this year. Plus whatever you have under ducks, straw, hay, is good for between rows, much, much less acidic than chickens. Just don't let it touch the stems of the plants just in case.
