New flock of pullets settling in

The new flock of 200 Isa Brown pullets are settling in well. They arrived yesterday and at first they weren't too sure about Bella - the Maremma whose job it is to protect them from marauding foxes, dogs, humans (if you can call them that) and birds of prey.
But within 12 hours or so the young hens were happily playing with her and inspecting her kennel.
The birds are well grown and I'm sure will start laying in week or so.
