My landlady has two such hens (they give you a pair so they don't feel lonely) and when she goes on holiday we get to enjoy free eggs. Absolutely delicious ones too! Even the best free range Bio ones don't come anywhere near in terms of quality.
Only problem of hens is they'll absolutely ravage your lawn if you leave them to feed alone for too long, so that was surprising.
