Just a warning, which you may already be aware of. With the early build-up of the brood and the early oilseed rape flowering, the bees are preparing to swarm very early. I have capped queen cells and once it warms up a bit, I think they will be off. Be ready for them! This weather is making it difficult to get into the hives, unfortunately. I have never had my bees prepare to swarm so early! Carole Smith
