I had a chat with the beekeeper who gave me the bees . He thinks I am looking at this all wrong . Robbing is not the problem it is a symptom of something else . Probably the hive has no queen . He suggested I had a look .
I try to do minimum intervention but agree with him in this case.
So I had a look .
and found nothing in the super . No wax no honey . So I took it off .
Looked in the main brood box and they are only on 8 and a half bars worth of bees . They have not grown since july when I added the super in July!.
So I put them back left the super off . and decided to leave them too it and see what happens
But the beekeeper promised me a new swarm next year.

If they dont make it I will try again
