Removing queen cups and cells, & undesirable queen patterns

As soon as Jack Frost finally leaves town, I will do a complete hive check on all hives. I am looking for three things:
1) Queen evidence: (eggs, larva and pupa). The brood pattern should be full:


Full pattern brood frame




Spotty pattern brood frame

2) If I see the queen and/or evidence she is laying well, I remove any queen cups and cells:

Queen Cups:





     Queen Cell




3) Bee Space:
When there is only one or two frames without stored resources and/or brood, it is time to add a second brood box. I do not add the second box until the weather is above freezing at night. The second box must be added beneath the original brood box to ensure the babies are warm because, as we all know, heat rises!

If you find multiple eggs in honeycomb cells, kill all your bees because one of the workers is laying unfertilized eggs and you will never figure out which worker is laying.



Comb with several eggs per cell is very undesirable.
