I don't have the experience to judge by weight, if my hives have enough stores but I thought I should feed them just in case.
However the temperature is hovering as about 10 degrees. My understanding is I should feed syrup above 10 degrees and feed fondant below 10 degrees. But if today is 8 degrees and I put fondant on, then tomorrow is 12 degrees so I change to syrup. I could be running back and forth all winter. Any advice for the obviously clueless?
