Checked Sally hive yesterday. Those bees are driving me nuts. Instead of drawing out the empty frames, they are building 'double decker' comb next to the empty frames. Weird...... Guess they don't like empty frames.. I also did not see any brood in the top deep, I'll have to go into the first deep and see what is happening. I wonder if this hive is being strange due to the limited food sources?
Here is a picture of the double deep comb:
