I joined late last summer. You all told me not to rush into beekeeping, but to read, join the local bee keeping association, find a mentor, read, start with two Langstroth hives, read, attend beekeeping classes, and read all I could about honey bees. I did, and my hives are doing great, I think (with my limited knowledge). To my question, I am useing 8 frame deeps for brood chambers and supers each hive now has 2 brood deeps and one honey super that is also a deep (I will use med supers after this year) one hive has many more bees. Not that that the other has too few, just that one has more. The front half of bottom brood chamber and landing board is covered with bees, some3-4 bees deep during the late afternoo/evening. I have screened bottom boards and placed shims to lift up inner cover for more ventilation. No one uses top entrances that I have talked to, but today I gave a top entrance to the one crowded hive.It just seemed more logical that foraging tired bees not have to fight the crowded landing strip to unload their stores. How long will it take for the bees to find their new entrance and did I give them what they needed?? They are working all new foundation and have not quite drawn out enough frames for me to give them another super and I didn' t want to put an empty box of frames for them to have to protect/defend with an unfamiliar entrance. How long do I wait to give them the next super?
