I don't give Chicory much fruit. The occasional grape. Parsley and a bit of carrot are his treats. He's 8 now, and fairly thin. We limit pellets and give unlimited hay. If he goes off his food, I pick blackberry leaves for him, cut out the spiny main rib, and feed those. I read somewhere that they were medicinal and would help with bun stomach upset (was a British source). Has worked every time. He's never had loose stools though, so not sure about that.
