Entrance reducers

[SixFooter]

Are entrance reducers used on the Darlington type up and over floors. If so, is the top slot reduced or the bottom slot ? If not, why not?

Please

No is the short answer.
Mine stay open the full width of the hive throughout the year. it's an underfloor entrance so the same as an OMF, it's in a 'lobby' so no draughts.
I have some hives in pretty high altitude apiaries, one. especially does get a fair bit of wind - never had an adverse effect on them
