Jack we have the potential for a lot of winter yet. Take a peak with a flashlight on one of these + 50% days and make sure they have enough honey. Replace dry sugar if needed. Let nature take its course with the pollen. I see the filbert peckers are out so....
Since they are probably starting to raise brood, and if our weather stays mild, they may need feeding. They'll take it when they want it. If they are hungry they'll get into any mix you put out.
And, I am putting my YJ queen traps out early too. I have not seen one yet, but this warmer weather may bring them out early.
