I am going to start growing duckweed, and it seems pretty easy. I have just a couple questions, though, to make sure I'll be doing it right! What should I use as a fertilizer? I will be growing it in a plastic kiddie pool that has about 15-20 feet of surface area. I don't have any growers by me - I'll have to buy some online and get it shipped to me. Should I wait until spring to start? Before I feed it to my chickens, do I have to dehydrate it at all or just skim it and give it?
