James and I built them a home with our own fair hands.

Philip

Chocolate

Chocolate was chosen by me but named by sophie, Philip was chosen by james and named by me. I asked soph what she wanted to call them and she said "brown one, chocolate" so the name stuck 'cos she was so cute about it.
no I am not growing them for food, but it IS a good idea.
oh, and there's now a bit more wire fencing to stop them chewing the bottom of the shed.
