Went out to check bees after all the tornadoes went through! It was still warm, 62. Hives were ok but noticed that one hive had bees take flight and go into the one next to it with no problem. Never seen them leave. Are they robbing? Thought I would check weight. Both are light. This week the high will be low 50's. I have been feeding these 2 hives with syrup but read 50 degrees is too cold for them to take heavy syrup. Should I get candy boards on them? Whats better, candy boards or fondant?
