Sadly we lost some birds to foxes when they were free-ranging during the day, so they now have a large, secure pen and come out to free-range under supervision when avian influenza housing orders aren't in force.  When housed they live in a large, airy barn with lots of stimulation.  They love looking for worms on the muck-heap and having dust baths in the haybarn, not to mention scrounging corn off us.  All our hens are named and have very individual characters, from Lucy the leghorn cross who will happily sit anywhere for corn, including on my head, to Bambi the amber who loves fuss, and Mara the legbar cross, the reformed bully, whose mission in life is to get into the conservatory.  Two of the hens were bred ourselves to lay blue and green eggs.
