Having just brought out my hives from their in-door wintering room, the
loss count is 4%.
This is the count of actual "dead outs".
It would be unusual if the loss percentage remains so low, as losses
normally continue (weak colonies fail due to varied reasons) throughout
the following few weeks.
These losses may be due to -
Queen failure.
Cluster size unable to provide enough heat to generate / maintain the
brood area.
Too high % of winter bees : Spring bees.
Small cluster size and weather conditions. (-7 degrees celsius several
nights (07/04/2006) ago with predicted high of 20 degrees tomorrow
(10/04/2006))
Possible robbing of colonies in spring holding yard.
Other conditions resulting in stresses (eg. low nosema infections)
Colonies taking up diluted HFCS and dry Bee Pro.
Elms should be in flower in a weeks time.
