Dang guys, thanks. I'm really loving these worm bins. I've got another bin same size with about 3-4lbs of worms. I've been feeding them with kelp alfalfa and malted barley, plus kitchen scraps. I wanna leave them alone but I'm trying to figure out how fast they eat, so I'm in there all the time checking. I don't want to over feed them, but I also want them to multiply.
