Re: Finding brood? or other queen check methods (long)
Royal jelly is whitish in color. And generally in the center of the cell, after the egg has hatched, you can see a tiny worm-like larvae. Sometimes when you can't see the eggs, because of light, age of your eyes, or whatever, you can see larvae that is several days old. That also tells you that you have a laying queen.
Also, honey cells will be around the outside of the frame, brood generally in the center and toward the bottom. Imagine if you will a huge D laying on it's straight edge, in a frame. The arc of the D is pointed to the top of the frame, and the D is your brood nest. Outside the D to the edges of the frame is where honey and pollen is stored. The brood is kept in the middle, and toward the bottom of the frame generally speaking.
When a queen really gets going and the colony is going gang-busters, in the center frames of a colony the brood will be side to side and top to bottom in the frame, and honey will be stored in other frames.
