It's spring and honeybees are busy building wax comb so they can expand their numbers.
One of the challenges beekeepers have is deciding when it is time to add a new story to the hive. Some say when 80% of the frames are full of bees it is time to expand.
Bees themselves have their own way of letting beekeepers know when they need more room. They start building comb straight up from the top of the frames.
They look ready for more room, don't you think?
