Greetings: 
Somehow  the first posting lost some of the words 
so here  is the correct form 
I'm  presently building small mating hives. I am familiar with Apedia  etc. 
I reread  Jay Smith's book on queen rearing several times. 
In the  book he states the following: 
<A small mating hive should not have a ventilator, as the air will  blow in 
through it and cause <the bees to realize their weakness and they  will 
abscond.  
What's  the opinion out there from your experience nowadays 
Are  ventilators necessary or is the -half inch entrance hole on an angle in 
the  middle as he states -enough.
