Hived these bees on a Saturday from a 5 frame nuc. Just sandwiched three empty frames between the foundation frames and checked them 5 days later. All of them looked like this. Installed another brood box on top and moved 2 foundation frames up into it and put two more empty frames (foundationless) into the lower box. Can't belive how fast these girls drew out the empty frames, and all had eggs in them. Feeling pretty good for a first try.
