For the third time Barney has managed to open the gate into the unused chicken run in the small field and trap himself inside by closing the gate behind?  Not sure how the gate closes as its a really tight fit in the frame but…there it is, he is inside the run and Larry outside.  So I have now put a metal hurdle against the gate but, no doubt, if he is clever he will move it and if he is stupid the barrier might keep him out.
