Hi Beeks,
I have seen some robbing screens that are better suited for traditional wooden bases. I also have Hive Doctors bases however (Original x1 and Smart x 2) which have a lowered base for the entrance, rather than flush flat wooden. I have not had any robbing in mine, however my friend's apiary 30 meters away has had one of his weaker hive robbed out just a week ago.
What robbing solutions do people suggest for Hive Doctor bases? I live 5 minutes away and it's not practical to check daily for any odd behaviours. So just seeking proactive strategies for my 3 hives.
