How much "green" food is too much? I know with rabbits too much can cause diarrhea. Once in a while I hang up romaine lettuce that they like to tear at also cabbage. But how often is it okay? Also I read that chickens shouldn't have citrus but our neighbors across the street give them everything. They told me that in Russia they throw out all kinds of leftovers for their birds. That seems a little iffy to me.
