I checked "Other" because I ferment a ground, whole food feed for their breakfast, then give them layer pellets the rest of the day. (I've found it too rich to feed them more fermented feed than that--lost one to fatty liver, and it's pricey!) Back when I made sourdough bread, I used to give them the discarded starter and they absolutely loved it! They live pretty long and are pretty healthy, so this works for me so far.
