Your bees are actually perfectly capable of taking care of themselves in just about any situation. They know how to find their own ‘food’ and water. They also know how to care for their own. They will take care of adding to your hive by reproducing. They will even ensure that the hive is defended against problems from the outside.
If your bees seem to be doing well on their own you want to make sure that you are leaving them on their own as much as possible. This is going to allow them to get everything they need and it will make them more productive. They’ll produce a lot more honey. They do need to be comfortable with you however as you need to make sure that they are feeling safe when they work with you. This includes when you are harvesting honey.
