Re: laying worker
Just had this conversation with Sue Cobey yesterday. Got essentially same answer as Michael. Could also try suppressing the pheromones by adding some mixed brood and start weaning them. Thought I had a "laying worker" last week (had multiple 2-3 eggs) but checked them today and found all single eggs (bottom and centered). Think it was just a very excited young queen getting fired up.
