Dunkel,
Spring was at least 2 weeks early here. I started seeing drone brood in my hives Feb 6th. I grafted earlier than I had planned with somewhat dismal results. The weather turned cold again as soon as I grafted. However, I think it had a lot to do with my cell builder. As the weather warms up my acceptance rates are much better. I have a feeling that I was ready for queen before my bees were. Funny how that works. Its hard to wait for the bees sometimes. I see my hives exploding early and I don't have enough queens to keep up. Now I'm hoping I have enough bees for all the queen cells I have.
