£200 of farm fencing supplies later we planned to rebuild the whole run, from this point on the be referred to (as all the neighbours are doing) as the Lion Cage, because what else do you call an enclosure made up for nine 8ft poles!
On the plus side no foxes are jumping this fence and as we had to make the run slightly larger I am already harbouring plans to get a couple of ducks come the spring, we'll see how it goes.
