jeff,
this is how i winter bees:
1. 2 deeps wrapped in colony quilt from b and b honey farm
2. entrance reducer on at 3 inches
3. 2" feeding rim/shim on to add sugar bricks
4. inner cover over the feeding rim; inner covers have a 2 inch opening (or so.......
) cut out for bee flight/ventilation
5. insulation box over the top of the inner cover that holds 2 inches of pink insulation
(ps. in the past i have used a 'quilt box' with clean straw packed in an extra super placed on top of the inner cover over the hives. it works. i have
not used shavings.)
6. outer cover on top the insulation box
sugar bricks..........these work very well for me, the bees 'process' the sugar just fine............and i am in a very cold climate.
thread here on sugar bricks:
SUGAR BRICKSi place the sugar bricks directly on top of the frames of the second deep, the feeder rim gives the room for the bricks and the bees seem to like this extra space to cluster.
