Waldemar said: >>Do you mean laying workers or drone-laying queens? ---------------------------- Besides the obvious (one's a worker and the other is an old or injured queen), what's the difference in this scenario? We had either a laying worker or a drone-laying queen this past spring after requeening last fall (kinda strange, isn't it?) only to find a horrendous amount of regular worker cells being converted in the middle of two frames to drone cells; beautifully capped and ready to hatch. Requeening yet again solved our problem but can we be sure we didn't have a laying worker laying all those drones? So the question is: can you have a laying worker in the same colony with an infertile queen? Dave Lehr Carroll County, MD -- Visit www.honeybeeworld.com/bee-l for rules, FAQ and other info ---
