Top is last week, bottom is this week. I have to wonder if we're into the nectar dearth period, or if they've been moving honey around on me again... It's possible they moved honey from the ends to fill in the centers which appear to be more capped now. Raw nectar has to be cured down to 18% moisture or less to make it stable as finished honey for storage, so they initially need more room for nectar. Nectar can be between 60-80% water, so honey takes up a lot less space!
