I opened up one and was checking out the brood pattern I noticed numerous queen cups in this one particular hive. There was probably 10-15 queen cups (no capped queen cells). this is a strong hive but they have plenty of room left in the honey super and there is plenty of capped brood, larva and eggs to show me that they are not queenless. Is it common to find numerous queen cups in a hive? or should I consider splitting this hive soon?
It is completely normal for bees to build "practice" queen cups. I don't know if it's just in case, or if they just want to stay tuned up on their skills. I see them in my hives quite regularly. Nothing to worry about.
