This is my first year playing around with queen rearing and trying to expand my operation. I've had luck grafting cells and getting them to take, though I only have about a 50% success rate in cell production. My biggest issue though is that I am not at all impressed with the size of the cells. They are really pretty tiny cells. I realize that there are potentially several different reasons for this, but I was hoping someone who has had experience with this might make a few suggestions for obtaining better results.
