The days are warm and long. But there is that chance of a cold snap happening. You will notice the bees bringing in more nectar and pollen. The queen should be laying at full capacity and you’ll see your hive population growing.
As the beekeeper, keep feeding your weaker hives. Stronger hives you shouldn’t be feeding. No supers should be on your weak hives. Inspect your hives, and look at the brood boxes. Can you find your queen? do you see eggs? how is the laying pattern? is it solid or scattered? if it is not solid, you may want to replace your queen. If you are finding your weak hives continue to struggle, you may want to consider combining the weak hive with another. Stronger hives are better at keeping away pests and diseases. Swarm season is here! swarming is the method bees use to grow their populations. It is not that you did a bad job with the hive, this is completely natural. So keep some extra hardware on hand so that if and when your hive swarms, you can capture it and provide a space for the swarm. To help prevent swarming, add one or two honey supers to your hive to give the hive more room and feel less cramped.
