"I pulled a nuc from hot hive almost three weeks ago. Since then I did some hive equalization, so the nuc is more of a hive now. There are four new foundations in this hive that are not getting pulled, albeit it's been cold for over a week. Just today it warmed enough that I could tell a flo is on and will be for a few more days. Would giving them 1:1 syrup for a week or two be neccessary with the flo?
About a week ago I gave them syrup, 3 holes, and it was gone by the end of the day. Then we had pretty hefty cold snap. Starting today we will be back into the high 60's, so I'll pick up feeding. I'll be taking a peek at this hive today as well"
with or without a flow on jen, i feed new colonies syrup until they stop taking it especially with foundation that needs to be drawn and don't stop feeding until it is drawn, and may not stop feeding until they are strong and ignoring the syrup. in your climate, with your drought, feeding probably is your best option and 'insurance'. also, nucs/divides/splits often do not have the forager force to forage for and care for all in the colony even with a flow on. the syrup helps.
