the pattern of the brood was what i was interested in. is it tight, or scattered? is she filling in as bees hatch out?
the queen will not lay more than the bees can care for. if something happened that reduced your bee population (skunk, for instance) the queen would lay less until numbers were up.
in that case, replacing the queen would be a waste of money. on the other hand, if she is not doing a good job of laying, you do need to replace her.
is the skunk still bothering? the carpet tack strip on the landing board is one of the better suggestions i have heard here. you might try that.
