6 piggies can happily eat a whole pepper, or half a pepper if combined with some leaves or cucumber, as a main meal- my 8 piggies eat 4 or 5 peppers a week, plus 2 or 3 cucumbers, a couple of bags of mixed salad leaves, a big bunch of herbs, a couple of little gem lettuces, a bag of beansprouts, some babycorn or carrots or pear as a treat... it is safe and healthy to be quite generous with peppers, a great source of vitamin C!
