So people asked for the method I used in double queening my hive here goes.
 
     1. I took my strongest overwintered hive ( it was over wintered in 2
hive bodies) and about 3 weeks ago I split all the bood and bees evenly ( or
as evenly as posible) in 2 hive bodies.I then took an inner cover that was
notched for an enterence and placed it on top of the hive body with the old
queen in it (I also added a hive body to that section so the old queen had
room to lay in 2 hive bodies). So I got 2 hive bodies with the old queen
laying in them an inner cover with a notch for an entrance for the bees at
the top and anouther hive body. I covered the hole in the inner cover to keep
the bees seperate. I then added a new queen to the hive body that was
queenless.
 
   2. A few days later I checked to see if the new queen was out. She wasn't
so I released her and let her go at it. 3 days later checked to make sure she
was laying and everything was good so far.
 
  3. About a week and a half after I intoduced the new queen to the queenless
hive body I was ready to join them and the original colony back together. I
got a wood bound queen excluder and notched an entrance on one side. I
sprayed the bees with vanilla water to confuse the scent alittle put the
excluder over the original collony that housed the old queen and then put the
hive body with the new queen over the excluder.( need to make sure that there
is an entrance for the top or drones can't get out)
   4. 2 days ago I added a secound hive body for the new queen. So my collony
is now 4 hive bodies tall 3 of which are almost full of brood and a fourth
that is starting to get filled. And I haven't even put honey supers on yet.
 
 People say just before the end of the honeyflow to remove the excluder and
let the queens fight it out but I am going to just split this hive during the
fall flow and try the same next year.
