what makes it a weak hive to you?

How many frames does a weak hive have, or how do you tell that you have a weak hive when you look in and pull frames an see lots of bees all over the hive. Is there a set amount of frames to go by or what??

In one of my hives the brood box is 10 frame and only 8 of them are full of bees/brood/some honey also---the next brood box ontop of the bottom one only has 1/2 that amount. Does that make it a weak hive?? the Med I have on top of the two is just about full of caped honey.

The other thing I would concider is this hive swarmed two times this year.

thanks JB:}
