The warm weather

This warm weather is energizing beekeepers to go out and put pollen patties on their hives and start feeding syrup. It may be a good idea to hold back for a couple weeks.
 This is Minnesota, the upper midwest, winter has a way of showing up again. Feeding syrup and pollen, early, can get the queen laying brood at a greater amount than normal for this time of year. If the weather stays warm, a hive could get overpopulated too early and the hive may be swarming by mid April, before queens are available. If the brood population increases drastically in a hive, a cold snap could jeopardize the survival of the colony.
It may be bad to stimulate the hive to get the bees rockin and rollin. Maybe a more prudent approach is called for.
What can you do right now. You can check the food in the top box. Lift the box to make sure it is still heavy with honey. A frame or two of honey can be moved  from another hive or from the lower part of the hive to bolster stores in the top box. Put the honey near the main cluster, do not put it in the main cluster. If the hive is low on food and the survival of the colony is in doubt, feeding syrup is the option. Better to feed than risk the bees starving.
Other than that, not much else should be done.
Pollen patties go on around March 1st, feeding can begin then also.
The forecast for next week has possible big snow storm in the forecast.
