So I've started growing some duckweed that I'm hoping to be able to feed my chickens with. I was horrified last week when I looked into my barrel of duckweed to find several of these swimming in it. Yuck. I'm so glad to at least know what they are now. Does anyone know if it will hurt my chickens if they eat these? I was afraid I was going to have to dump it all out and start over.
