Twice a week, I get a big ol' bag of vegetable & fruit pulp (and other veggie trimmings) from a friend who uses one of those juicers for her family. Usually it's mostly carrot pulp and pineapple pulp, with orange sections, bananas pieces, and some additional salad trimmings.
The chickens go wild over it! Some of them don't care for the citrus or pineapple, some don't care for the bananas, but for every 1 fussy eater, there are 6 that will eat ANYTHING.
I've found that sometime you have to experiment not only with different foods, but with giving them foods in different ways. I throw larger carrot pieces into my food processor for a few seconds, since they don't seem to like picking at the bigger pieces. And even chickens that won't eat small carrot pieces or carrot peelings will scarf up the carrot pulp from the juicer like there's no tomorrow.
I've also found that if there's a veggie they don't like, they will sometimes eat it if it's cooked slightly first. I got a bunch of leftover pumpkins from people's fall decorations, but they weren't interested in the raw pumpkin. So I cut them in half, scooped out the seeds, and baked the pumpkin halves, then cooled and put the seeds back in the halves. The girls go nuts!
I saw another thread that cautioned against feeding cabbage, but I've always fed cabbage (raw and cooked). They love it, and I've had no ill effects.
