Hi, Here in MN we need to hive packages in mid April if they are to be ready for our honeyflow on July1. As a result we often hive them in cool or cold weather. It doesn't seem to bother the bees as long as the feeder is directly over the cluster so they can get the feed while clustered. You can remove four frames from the box, set the package in the hive body and close the cover while you get the feeders ready etc. The package will warm the combs some. When you remove the queen cage, put her in your pocket to protect her from the weather and dump the bees into the box. Release the queen into the bees, put the frames back in, add the feeder and close it up. We hived 40 packages a few weeks ago in cold rain (30's) and wind but they seemed to handle it ok. good luck Blane ****************************************** Blane White State Apiary Inspector Minnesota Department of Agriculture Division of Plant Protection 90 W Plato Blvd St Paul, MN 55107 ph 612-296-0591 fax 612-296-7386 [log in to unmask] ********************************************
