Hello, my family us quite new to bee keeping. We have 4 hives this year. We know quite slot about bees, but there are some holes in our knowledge. Mind helping ? 1. Should queen gates ( picture below) be put on the entrance to stop swarming? What happens if the colony is over packed and can't swarm? 2. When should a second box with more frames & a queen excluder be added to the bee boxes? Months after they start or the second year? 3. If I have a one story box for my 4 hives I won't get any honey right? They will be used for brood and there won't be enough honey to collect? I probably sound like the biggest noob, but bees are my passion and I'm trying to get everything down!
