I can't imagine it would harm your chucks, but you could probably eat it yourself. I think (if I remember rightly) that when they opened one of the Pharaohs tombs there was honey in jars, and when they tried it they found it was still edible
If yours is just set very hard and crystallized just put it somewhere warm - I rest the jar on the back of the Aga overnight, but you could put it in a pan of water and put on the lowest heat on a ring for a few hours. The honey should go back to its original edible state.
Or make some honey based flapjacks, or honey ice-cream, or honey cake........
All the best
