I had a nuc that went queenless after I installed it so I got a new marked queen and installed it. I checked a week or so later and found an unmarked queen so I must have missed the queen cell. One thing I noticed on the last inspection is that some of the bees are almost completely yellow, very light and not much black striping, I'm guessing that these are the bees emerging from the new queen, is this normal for the bees to be this color?
