Re: What to feed a Bar of queens
Prioritize your life. Get those queens in hives asap. Not when convenient, but when you can.
That being said. Is there "food" in the box w/ the queens? Anytime I have received queens in JZBZs cages, there are bees loose in the box surrounding the queens. and w/ them, usually, there is a sponge, for a water source, and damp confectionery sugar, as a food source.
Were they in wooden cages, I would recommend a watering and feeding w/ honey every day. Dip your finger in a cup of water and dab it on the screen. Get some honey on your finger and dab that on the screen. I know guys who keep queens fed for a week that way. Removing dead attendants along the way.
