My bee club suggests syrup feeding starting January first. Not sure if I will that early, maybe on nice days only. This year I left the extra hive boxes with telescoping covers over my feeder lids, so putting syrup on won't involve opening the hive...
I put fondant with pollen sub on yesterday, as I have every couple of weeks on nice days. One of my hives is strong, but hot. The others don't have the numbers I would like to see.
